AB  - A new Bi-rich part of Bi2O3-PbO phase diagram was determined using differential thermal analysis and X-ray powder diffraction techniques. Four solid solutions, alpha-Bi2O3, gamma-Bi2O3, d-Bi2O3 and ss(ss)-Bi8Pb5O17, can be distinguished below 37.5 mol % of PbO and one compound, ss(2)-Bi8Pb5O17. Two of them, d-Bi2O3 and ss(ss)-Bi8Pb5O17 are high-temperature phases. The large field of gamma-Bi2O3 stability was implemented making the crucial difference comparing to phase diagrams from the Bi2O3-PbO system published so far.

AB  - The dissolution of electric arc furnace steel slag (EAFSS) in highly alkaline MOH solution (M = alkali metal Na or K) has been investigated with emphases on the influence of the initial alkali concentration, solid to liquid (S/L) ratio and temperature on the kinetics of Si and Al dissolution from EAFSS. The shrinking core model (SCM) was used to analyze experimental data and the results have shown that the Si and Al dissolution from EAFSS was greatly influenced by MOH concentration, alkaline ion type and temperature. The dissolution process was controlled by the bulk diffusion through the product layer crystals. The activation energy for Si and Al dissolution was 55.27 kJ/mol and 48.05 kJ/mol in NaOH solution and 90.68 kJ/mol and 33.62 kJ/mol in KOH solution, respectively.

AB  - The thermal resistance of alkali-activated binders based on fly ash (FA), electric arc furnace slag (EAFS) and their FA/EAFS blends was assessed. Compressive strengths of samples before and after firing were measured. The samples were characterized by X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), energydispersive X-ray spectra (EDS), thermal (TG/DTA) analysis. Besides, the sintering shrinkage were recorded by thermomechanical analyzer (TMA) during non-isothermal sintering up to 900 ºC with heating rate of 15 º/min, in an air atmosphere. The main reaction products in FA and EAFS based alkali activated binders are the sodiumalumino-silicate-hydrate (N–A–S–H) and calcium-alumino-silicate-hydrate (C-A-S-H) type gels, respectively. FA/EAFS based binders are characterized by the presence of N-A-S-H gel with the high content of Ca. The EAFS based binders exhibited superior performances in terms of compressive strength than FA based binders. Thermal resistance of FA based binders was improved by the slag addition. This research was supported by a Ministry of Science of Montenegro under the contract No. 01-460.

AB  - This paper presents a study on thermal stability of alkali activated slag (AAS) prepared from electric arc furnace slag (EAFS) using a mixture of alkaline sodium hydroxide and sodium silicate solutions. The samples were investigated by means of XRD, SEM, TG/DTA and porosity analysis. Compressive strengths of MS samples before and after exposure to elevated temperatures ranging from 600 degrees C to 1000 degrees C were determined. The significant microstructural modifications highlighted by changes in porosity due to the sintering process are responsible for the strengthening of MS sample after heating at 600,800 and 1000 degrees C. Moreover, in MS sample after heating to and above 600 degrees C wustite transforms to spinel.

AB  - The remelting of iron and steel scrap in the electric arc furnaces generates the non-hazardous waste – electric arc furnace slag (EAFS), which can be disposed of to appropriate landfills. Currently, this slag found its application in conventional concrete production to improve its mechanical, chemical and physical properties, as an additive to asphalt base mixture and in cement production. In this study we have investigated the effect of alkaline dosage on the strength and thermal resistance of EAFS based geopolymers. The results have shown that these materials are mainly amorphous with some crystal phases remained from the undisolved EAFS such as larnite, gehlenite, wuestite, monticellite, calcite. Compressive strength of these materials is strongly influenced by the alkaline dosage. An increase of NaOH concentration in the interval of 7-10 M leads to the increase of geopolymer’s strength. The maximal compressive strength of EAFS based geopolymer was obtained using the 10 M NaOH. Further increase of alkaline dosage to the value of 13 M NaOH results in the slight decrease of the geopolymer strength. Additionally, depending on the synthesis parameters, EAFS based geopolymers exhibit improved durability in high temperature environments in comparison with conventional cement based materials. All investigated samples exhibit a shrinkage which is attributed to the change of porosity. The mass loss due to the loss of water was also observed. This research was supported by a Ministry of Science of Montenegro under the contract No 01-460.

AB  - A series of polycrystalline samples containing sillenite-like (doped gamma-Bi2O3) phases were prepared by high-temperature reactions from alpha-Bi2O3 powder and different oxides in six pseudo-binary Bi2O3-MxOy (M = Mn, Ti, V) and six pseudo-ternary Bi2O3-M1(x)O(y)-M2(x)O(y) (M1 = Pb, Zn, Ti and M2 = Zn, Ti, Si) systems. The products were characterized by XRD, SEM/EDX, HRTEM, SAED and DTA techniques. It is shown that for pseudo-binary systems, the phase composition of specimens depends on dopant content, while, for pseudo-ternary systems, depends on dopants radii, as well. In pseudo-binary systems, singlephase sillenites are obtained if the dopant content is in accordance with formula Bi12M4+O20, for M = Mn and Ti, and Bi-12(M-0.8(5+))O-20, for M = V. However, two coexisting sillenite-like phases, doped compound and nominally undoped solid solution, are found if a half of that dopant quantity is applied. In pseudoternary systems, the phase-pure double-doped sillenite specimens are identified if ionic radii of dopants differ less than 40%. Otherwise, two coexisting sillenites were obtained. The possibility to prepare the undoped gamma-Bi2O3 phase was also discussed.

AB  - This research has provided information about the influence of alkali cations (Na+ and K+) on the mechanical properties and durability of fly ash based geopolymers. The results have shown that alkali cations have a strong influence on the mechanical properties of fly ash based geopolymers. K-geopolymers generally reach a higher value of compressive strength in comparison to Na- geopolymers. On the other hand, microstructure and phase composition of fly ash based geopolymers are not influenced by the nature of alkali cations. The ratio of main gel structure forming elements is practically not affected by the nature of alkali cations. Durability of fly ash based geopolymers in different aquatic environments is greatly dependent on the choice of alkali cations. Na-geopolymers are generally more resistant in water and aggressive environments than the K-geopolymers. The best durability of fly ash based geopolymers was observed in sea water.

AB  - A polycrystalline single-phase sample with nominal composition Bi24PbO37 was synthesized from Bi2O3 and PbO by a high-temperature solid state reaction at 690 degrees C for 1.5 h. The compound adopts Bi12SiO20-type structure [cubic, space group I23 (No. 197); a = 10.24957(3) angstrom] and was refined to R-p = 7.96%, R-wp = 10.4%, R-exp = 8.43%, R-B = 3.06%, and S = 1.23. The distributions of Pb2+ and Bi3+ over cationic sites based on the X-ray powder diffraction data were determined using a combination of the Rietveld refinement and bond valence calculations. The results showed that the asymmetric unit contains two mixed cation sites: the fully occupied 24f site and the partly occupied 8c site, with the unit-cell content (Bi23.68Pb0.32)(Bi1.28Pb0.72)O-38.48. The structural constraints favor a preference of Pb2+ ion for the 8c site, i.e. only 1.3% of Bi3+ is substituted by Pb2+ at the 24f site and 36% at the 8c site. At the 24f site, the cations are surrounded by 5 + 2 or in a very small amount by 5 + 1 + 2 oxide ions, forming a base bicapped square pyramid or a bicapped highly deformed octahedron, respectively. At the 8c site, the cations with three oxide ions form a trigonal pyramid with the cations at the apex.

AB  - A series of novel ternary Co(II), Ni(II) and Cu(II) complexes containing 2,2'-dipyridylamine (dipya), 2,2'-bipyridine (bipy), and 1,10-phenanthroline (phen), as aromatic diamine ligands, and dianion of isophthalic acid (ipht) have been prepared by ligand exchange reactions from diluted H2O/EtOH solutions. The complexes were characterized by elemental analysis, IR spectroscopy, magnetic susceptibility measurements and TG and DSC analysis. Three complexes, Cu(dipya)(ipht)center dot H2O (1), Co(dipya)(ipht)center dot 2H(2)O (2) and Cu(ipht)(phen)center dot 2H(2)O (5) are polymeric with bis-monodentate ipht, while the other two complexes M(bipy)(iPht)center dot 4H(2)O, M=Co(II) (3) and Ni(II) (4), contain ipht as a counter ion. All Co(II) and Ni(II) complexes are (pseudo)octahedral, while Cu(II) complexes have square-pyramidal or distorted octahedral geometry. The variable temperature magnetic susceptibility measurements showed very weak antiferromagnetic behaviour for all complexes. Dehydration processes, decomposition mechanisms and thermal stability of 1-5 are assumed. One complex from the above series, [Ni(bipy)(H2O)(4)](iPht) (4), and one additional complex, [Co(bipy)(iPht)](n) (6), are obtained as single-crystals and their structures are determined from X-ray diffraction data. In both structures M(II) centers are in deformed octahedral environment and they are linked by hemi-ipht ligands (4) and two different bridging ipht ligands (6). Three-dimensional networks in 4 and 6 are governed by strong noncovalent interactions. The cations and ipht anions in 4 are connected by hydrogen bonds building double layers parallel to ab-plane that are further packed by pi-pi interactions. In 6 double chains extending along b-axis are strengthened by interchain pi-pi interactions constructing a three-dimensional framework.

AB  - The novel title coordination polymer, {[Cu(C8H4O4)-(C10H9N3)]center dot H2O}(n), synthesized by the slow-diffusion method, takes the form of one-dimensional zigzag chains built up of Cu-II cations linked by benzene-1,3-dicarboxylate (ipht) anions. An exceptional characteristic of this structure is that it belongs to a small group of metal-organic polymers where ipht is coordinated as a bridging tridentate ligand with monodentate and chelate coordination of individual carboxylate groups. The Cu-II cation has a highly distorted square-pyramidal geometry formed by three O atoms from two ipht anions and two N atoms from a di-2-pyridylamine (dipya) ligand. The zigzag chains, which run along the b axis, further construct a three-dimensional metal-organic framework via strong face-to-face pi-pi interactions and hydrogen bonds. A solvent water molecule is linked to the different carboxylate groups via hydrogen bonds. Thermogravimetric and differential scanning calorimetric analyses confirm the strong hydrogen bonding.

AB  - A powder mixture of α-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the mechanochemical reaction led to the formation of a nanocrystalline δ-Bi2O3 phase (fluorite-type solid solution Bi0.78Hf0.59Zr0.63O3.61), with a crystallite size of 20 nm. The mechanochemical reaction started at a very beginning of milling accompanied by an accumulation of ZrO2 arising from the milling tools. The samples prepared after various milling times were characterized by X-ray powder diffraction and DSC analysis. The electrical properties of the as-milled and pressed Bi0.78Hf0.59Zr0.63O3.61 powder were studied using impedance spectroscopy in the temperature range from 100 to 700°C under air. The electrical conductivity was determined to be 9.43×10-6 and 0.080 S cm-1 for the temperatures of 300 and 700°C, respectively.

AB  - Concurrent milling of Bi4Ti3O12 was carried out in a planetary ball mill with hardened-steel 13 or 6 mm diameter balls with a goal to investigate how the system responds to the constrains imposed by milling. Milling intensity for various milling parameters was derived from the electrical power measurement. The reverse amorphous ↔ crystalline phase transition induced by milling is governed by impact energy and frequency. Below a certain threshold value of impact energy crystallization does not occur, whereas a higher impact frequency accelerates amorphization. Mechanochemical reactions are predominantly discrete processes, which occur at the moment of impact. © 2009 Elsevier B.V. All rights reserved.

AB  - Mechanochemistry represents an alternative route in synthesis of nanomaterials. Mechanochemical routes are attractive because of their simplicity, flexibility, and ability to prepare materials by solid state reactions at room temperature. The aim of this work is the mechanochemical synthesis of nanostructured titanium oxides of different composition starting from mixtures of Ti and TiO2, TiO and TiO2 or Ti 2O3 and TiO2. Emphasis is on the Magneli phases Ti4O7 and Ti5O9 because their mixture is commercially known as EBONEX material. The materials prepared were characterized by XRPD, TG/DTA analysis, SEM and optical microscopy. Titanium monoxide and several Magneli oxides, Ti4O7, Ti 5O9 and Ti6O11, are successsfully prepared. The results are very interesting because the EBONEX materials were prepared at lower than usual temperature, which would decrease the effective cost of production.

AB  - During an investigation of the SrO-CuO-P2O5-H 2O system, single crystals of distrontium hexa-hydroxido-cuprate(II), Sr2 [Cu(OH) 6], were obtained by the hydro-thermal method. The blue prismatic crystals of Sr2 [Cu(OH) 6] adopt the same structure type as Ba2 [Cu(OH) 6], Sr 2 [Zn(OH) 6] and Ba2 [Zn(OH) 6]. The Cu atoms, located at (0, 0, 1/2 ) (site symmetry ), form /mutually isolated and highly elongated Cu(OH) 6 octa-hedra, which are inter-connected to slightly distorted Sr(OH) 6 trigonal prisms, forming a layered structure. The location of H atoms from difference Fourier maps and their refinement allowed the precise determination of a three-dimensional hydrogen-bonding network in which all hy-drox-ide O atoms are involved. In addition, the hydrogen-bonding topologies in Sr2 [Cu(OH) 6] and other similar hexa-hydroxido-metallates with the general formulae M1[M2(OH) 6], M12 [M2(OH) 6] and M13 [M2(OH) 6] were analysed in detail.

AB  - The crystal structure of the mineral picotpaulite, TlFe2S 3, was solved and refined using single-crystal X-ray diffraction data collected at room temperature. The symmetry is orthorhombic, space group Cmcm, with unit-cell parameters: a = 9.083(6), b = 10.754(6), c = 5.412(4) Å, V = 528.6(6) Å3, Z = 4. The structure was refined to the conventional R factor 0.0532 for 226 independent reflections with I > 2σ(I) and 21 variables. Picotpaulite is isostructural with minerals rasvumite (KFe2S3) and pautovite (CsFe2S 3), as well as with a number of synthetic compounds belonging to the CsCu2Cl3 structure type. The structure consists of double chains of FeS4-tetrahedra running along [001] interconnected by TlS10 coordination polyhedra, which form zig-zag chains along the same direction. The Fe-Fe distances between neighbours along the chain direction and perpendicular to it are 2.706(2) and 2.693(6) Å, respectively, indicating strong Fe-Fe interactions. The average oxidation state of Fe is +2.5, achieved by electron transfer over the close Fe sites. Thallium coordination polyhedron can be described as a combination of a square antiprism adjacent to a trigonal prism. The 6s2 electrons of Tl behave as an inert pair and the atom is situated in the centroid of its coordination.

AB  - A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the following order of increasing relative stability of the doped gamma-Bi2O3 phases was established: Sb 51  lt  Co2+ Mn4+  lt  Fe3+ approximate to Si4+  lt  Ti4+  lt  V5+  lt  Zn2+  lt  Ph2+. The unit cell parameters of the prepared samples were compared with available structural data, which were also further analyzed concerning the geometrical parameters and overall reliability. The analysis confirmed the socalled Radaev's model for the doped gamma-Bi2O3 structure, which assumes the presence of Bi2(3+) ions slightly displaced from the tetrahedral M site and corresponding vacancies (resulting from a lone pair on Bi2(3+)) in the coordinating oxygen positions. In addition, the analysis suggested that this model can be further improved. The existence of an approximate linear relationship between the unit cell parameters of the doped gamma-Bi2O3 phases and the ionic radii of the M cations was found.

AB  - The crystal structure of the complex [Ni2(btc)(dipya)2(H2O)6]⋅6H2O·DMSO (btc = tetra-anion of 1,2,4,5-benzenetetracarboxylic acid, dipya = 2,2’-dipyridylamine) was refined in the triclinic system, space group P1, using low temperature (170 K) X-ray diffraction data. The compound consists of binuclear complex entities and lattice solvent molecules making pseudo-layers parallel to the 101 plane and channels parallel to the b-axis. The observed structural features were compared with the previously reported results and formula [Ni2(btc)(dipya)2(H2O)6]⋅4H2O based on room temperature X-ray diffraction data. A possible arrangement of the disordered lattice solvent molecules located in the structural channels is described and discussed. It is concluded that the layout of these molecules is non-centrosymmetric, although the remaining and main part of the structure is centrosymmetric. .

The compound consists of binuclear complex entities and lattice solvent molecules making pseudo-layers parallel to the 101 plane and channels parallel to the b-axis. The observed structural features were compared with the previously reported results and formula [Ni2(btc)(dipya)2(H2O)6]⋅4H2O based on room temperature X-ray diffraction data. A possible arrangement of the disordered lattice solvent molecules located in the structural channels is described and discussed. It is concluded that the layout of these molecules is non-centrosymmetric, although the remaining and main part of the structure is centrosymmetric. ., Kristalna struktura kompleksa [Ni2(btc)(dipya)2(H2O)6]⋅6H2O·DMSO (btc = tetraanjon 1,2,4,5-benzentetrakarboksilne kiseline, dipya = 2,2’-dipiridilamin) utačnjena je u trikliničnom sistemu, prostorna grupa P1, na osnovu podataka dobijenih rendgenskom difrakcijom na niskoj temperaturi (170K).

AB  - Concurrent mechanochemical treatment of either a stoichiometric 2Bi 2 O 3 · 3TiO 2 powder mixture or (pulverized) Bi 4 Ti 3 O 12 compound was performed in a planetary ball mill. Relevant structural parameters: crystallite size, amount of amorphous phase and the transformed fraction (as a result of chemical reaction between Bi 2 O 3 and TiO 2 ) of the powders milled for various milling times and intensities were derived from X-ray powder diffraction data. The obtained structural parameters were used to follow the kinetics of the reduction of crystallite size, amorphous phase formation and chemical reaction. In the powder mixture, during the early stage of mechanochemical treatment the Bi 2 (CO 3 )O 2 phase was found as an intermediate product which transformed into the highly amorphized Bi 4 Ti 3 O 12 phase as the milling progressed. On the other hand, mechanochemical treatment of Bi 4 Ti 3 O 12 powder induced a gradual deformation of the crystal lattice and destruction of the perovskite-type structure. However, in both cases, after a certain milling time, a very disordered, amorphous/nanocrystalline structure was obtained. It was demonstrated that in the steady state, the amorphous/nanocrystalline phase ratio depends on the milling conditions. Higher milling intensities induce 'nanocrystallization' of the amorphous phase, i.e., precipitation of crystallites with an average size below 20 nm. A kinetic model involving a nanocrystalline ↔ amorphous reaction, in which the forward and reverse reaction were first-order was postulated and used to analyze the formation of an amorphous phase.

abstract = "X-Ray crystal structure analysis of the complex [Cu(tpth)(phen)(H2O)]n, where tpht is the dianion of terephthalic acid and phen is 1,10-phenanthroline showed that two crystallographically different, but chemically identical tpht ions with monodentately coordinated COO groups exist; both tpht ions act as bridging ligands forming zigzag chains. The Cu(II) ions are in a deformed trigonal bipyramidal environment consisting of two N atoms from phen, two O atoms from different tpht ligands and one O atom from coordinated H2O molecule. The crystal data are as follows: C20H14CuN2O5, Mr = 425.87 triclinic system, space group P 1, a = 9.007(5), b = 10.557(5), c = 11.554(5) Å, α= 114.343(5), β = 92.942(5), γ = 114.516(5) º, V = 877.3(7) Å3, Z = 2 F(000) = 434, ρx = 1.612 g cm-3, μ = 1.281 mm-1, R1 = 0.0280 for 4363 reflections with I  gt  2σ(I), wR2 = 0.0785 for 5104 independent reflections and 254 refined parameters.
