AB  - The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3-15 wt% Fe2O3 were synthesized by a combination of sol-gel and combustion methods. The excess of water and urea were introduced in reaction solutions to enhance the copolymerization of aluminum and silicon species. The results of structural characterization revealed that the synthesized mullite powders were amorphous of a hybrid type. The specific surface area of the undoped mullite powder was 262 m(2) g(-1) with a maximum pore radius (d(p)) of 2 nm classifying it into mesoporous materials. The addition of iron has reduced the specific surface area, while the pore size value remained the same except for the sample with 3 wt% Fe2O3 (S-BET = 278 m(2) g(-1); d(p) = 3 nm). The presence of iron caused lowering the temperature of liquid phase formation, while present urea combusted providing the increase of the temperature locally that caused the sintering and formation of agglomerates of smaller particles. However, the results of the particle size analysis are not straightforward. The values of mean volume diameter (D[3,4]) indicated that the particle size increased to 6 wt% Fe2O3 (123.6 mu m), and then decreased and for the sample with 12 wt% Fe2O3, it was equal to 96.6 mu m. Thus, the added iron contributed to the more uniform particle size distribution. The SEM analysis has also shown the coarse powder particles consisted of the coalesced smaller particles.

AB  - In this study, the behavior of glass-ceramics synthesized from a glass frit of FFW (Final Flotation Waste) originated from the RTB Bor Company was investigated. Thermal shock resistance was monitored in order to assess the possibility of application of such waste material. Thermal shock of the samples was conducted using water quench test. Image analysis and ultrasonic measurements were used as nondestructive methods for quantification of thermal shock damage at the surface and in the bulk of the specimens. Phase composition of samples was determined by X-ray powder diffraction (XRPD). The degradation level of samples was about 43 % after 20 cycles of water quench tests. The results pointed out that glass-ceramic material exhibited good thermal shock resistance.

AB  - A cordierite/SiC composite was created in situ with reactive sintering at 1250 degrees C and 1300 degrees C. The cordierite precursor was made from commercially available spinel, alumina and quartz and was mixed with the comercial SiC powder to obtain composite materials during the sintering. It was found that cordierite particles bind efficiently with the SiC powder during sintering and that reactive sintering is an effective way to produce ceramics at a relativly low temperature. The goal of this investigation was to check the possibilities of using the silicon carbide-cordierite composite as a material resistant to the erosive wear. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Two kinds of SiC/cordierite samples were investigated, KS 50 and KS 30, with different mass contents of cordierite (w = 50 % and w = 30 % of cordierite). The mass loss and the level of surface degradation were measured before and during the experiment. The level of surface degradation of the samples was monitored using the Image-Pro Plus program for the image analysis. It was found that after 150 min the mass loss was below 1.3 mg and the surface degradation was below 7 %. The obtained results indicated that both samples exhibited an excellent erosion resistance during the cavitation experiment.

AB  - Amorphous powders of iron doped 3:2 mullite (3Al(2)O(3)center dot 2SiO(2)) were prepared by sol-gel combustion process using ethanol-water solutions of Al(III) nitrate, Fe(III) nitrate, TEOS and urea. Compositions up to 15 wt% of Fe2O3 were investigated. After combustion and heat treatment at 800 degrees C for 4 h, XRD analysis confirmed that the powders were amorphous. This is in agreement with the thermodynamic predictions that direct formation of mullite has not occurred during the aluminum nitrate - urea combustion reaction. XRD patterns of uniaxially pressed and sintered pellets at 1550 degrees C for 4 h revealed the crystal structure of orthorhombic mullite. The lattice parameters and unit cell volume increases as the mullite solid solutions were enriched by iron. The TGA/DSC analysis showed the reducing of crystallization temperature of iron doped mullites with increasing of iron content in reaction mixtures. The mullitization reaction is two-step process including formation of transient spinel phase below 1000 degrees C and mullite crystallization at temperatures about 1200 degrees C. The SEM micrographs of the sintered samples reveal elongated mullite grains with grain length up to 40 mu m. Increasing of the iron content in the reaction mixture enhances the grain size and the grains become elongated and better packed increasing the density of sintered samples.

AB  - Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 nanopowder as a starting material. We monitored the changes in the morphology of ceramic samples and their consolidation with additional thermal treatments at 650 degrees C and 1100 degrees C. The ceramics grain size remained in the sub-micron domain, even when elevated temperatures were used for annealing. The best results were obtained for the sample sintered at 1100 degrees C for 20 min, which had the smallest grain size, theoretical density, and the most intensive photoluminescence, along with the maximum hardness and appropriate fracture toughness. The Judd-Ofelt intensity parameters and branching ratios were calculated, taking into account the difference in the effective refractive index for the nanopowder and ceramic samples.

AB  - Covalent bond in SiC ceramic request high temperature for its sintering. In order to put down sintering temperature of SiC ceramics we choose cordierite as phase between SiC particles. Reactive sintering is an effective way to produce ceramics at relatively low temperature. We have created in situ SiC/cordierite composite at 1250 degrees C. Cordierite precursor was made from commercially available spinel, alumina and quartz. The possibilities of using silicon carbide-cordierite material as resistant to the erosive wear was goal of this investigation. The fluid dynamic system of the experimental methodology was used here to produce ultrasonic erosive wear. Mass loss and level of degradation were measured before and during the experiment. Level of degradation of the samples was monitored using Image Pro Plus program for image analysis. Average erosion ring diameter as well as average erosion area were monitored during experiment. Obtained results pointed out that after 150 min sample exhibited excellent erosion resistance compared to metal and ceramic samples.

AB  - The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine β-SiC powder at relatively low temperatures (1673-1873 K), was demonstrated. Obtained SiC powders consist of fine β-SiC particles and did not retain the fibrous morphology of starting sepiolites. Carbothermal reduction process, which was used in this study, is greatly influenced by catalyst addition (FeCl3, FeSi). In order to obtain pure SiC powders, it is necessary to completely remove all Mg-species, and catalytic influence of Fe is attributed to FeSi important role in reduction of Mg2SiO4 and MgO into Mg(g). Formation of SiC whiskers is observed only in samples with Fe introduced in form of iron-silicide (FeSi).

AB  - Two different types cordierite/silicon carbide composite ceramic materials (KS 50 and KZ 50) were used for this investigation. Both materials were exposed to the water quench test from 950 degrees C, applying various numbers of thermal cycles. When refractory samples are subjected to the rapid temperature changes crack nucleation and propagation occurs resulting in loss of strength and materials degradation. The formation of cracks decreases the density and elastic properties of material. Therefore, measuring these properties can directly monitor the development of thermal shock damage level. Dynamic Young modulus of elasticity and strength degradation were calculated using measured values of ultrasonic velocities obtained by ultrasonic measurements. Level of degradation of the samples was monitored before and during testing using Image Pro Plus program for image analysis. The capability of ultrasonic velocity technique and image analysis for simple and reliable nondestructive methods of characterization was presented in this investigation. It was found that both composite materials exhibit good thermal shock resistance.

abstract = "Two different types cordierite/silicon carbide composite ceramic materials (KS 50 and KZ 50) were used for this investigation. Both materials were exposed to the water quench test from 950 degrees C, applying various numbers of thermal cycles. When refractory samples are subjected to the rapid temperature changes crack nucleation and propagation occurs resulting in loss of strength and materials degradation. The formation of cracks decreases the density and elastic properties of material. Therefore, measuring these properties can directly monitor the development of thermal shock damage level. Dynamic Young modulus of elasticity and strength degradation were calculated using measured values of ultrasonic velocities obtained by ultrasonic measurements. Level of degradation of the samples was monitored before and during testing using Image Pro Plus program for image analysis. The capability of ultrasonic velocity technique and image analysis for simple and reliable nondestructive methods of characterization was presented in this investigation. It was found that both composite materials exhibit good thermal shock resistance.",

AB  - The effect of yttria additive on the thermal shock behavior of magnesium aluminate spinel has been investigated. As a starting material we used spinel (MgAl2O4) obtained by the modified glycine nitrate procedure (MGNP). Sintered products were characterized in terms of phase analysis, densities, thermal shock, monitoring the damaged surface area in the refractory specimen during thermal shock and ultrasonic determination of the Dynamic Young modulus of elasticity. It was found that a new phase between yttria and alumina is formed, which improved thermal shock properties of the spinel refractories. Also densification of samples is enhanced by yttria addition.
AB  - U ovom radu je ispitivana otpornost spinela, MgAl2O4, prema termošoku u prisustvu Y2O3 kao aditiva. Kao polazni materijal korišćen je spinel dobijen modifikovanom glicin-nitratnom metodom. Analiza sinterovanih uzoraka podrazumevala je određivanje faznog sastava, praćenje oštećenja površine uzoraka usled termošoka, određivanje dinamičkog Jungovog (Young) modula elastičnosti ultrazvučnom metodom. Nađeno je da reakcijom spinela sa Y2O3 dolazi do formiranja nove faze koja poboljšava otpornost spinelne keramike prema termošoku. Takođe je utvrđen pozitivan uticaj dodatka Y2O3 na densifikaciju spinelne keramike.

AB  - In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 degrees C, applying various number of thermal cycles (shocks). Level of surface deterioration before and during quenching was monitored by image analysis. Ultrasonic measurements were used as non-destructive quantification of thermal shock damage in refractory specimens. When refractory samples are subjected to the rapid temperature changes crack nucleation and propagation occurs resulting in loss of strength and materials degradation. The formation of cracks decreases the density and elastic properties of material. Therefore by measuring these properties one can directly monitor the development of thermal shock damage level. Dynamic Young's modulus of elasticity and strength degradation were calculated using measured values. Level of degradation of the samples was monitored before and during testing using Image Pro Plus program for image analysis. The capability of non-destructive test methods such as: ultrasonic velocity technique and image analysis for simple, and reliable non-destructive characterization are presented.

AB  - In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950°C, applying various number of thermal cycles (shocks). Level of surface deterioration before and during quenching was monitored by image analysis. Ultrasonic measurements were used as non-destructive quantification of thermal shock damage in refractory specimens. When refractory samples are subjected to the rapid temperature changes crack nucleation and propagation occurs resulting in loss of strength and materials degradation. The formation of cracks decreases the density and elastic properties of material. Therefore measuring these properties can directly monitor the development of thermal shock damage level. Dynamic Young modulus of elasticity and strength degradation were calculated using measured values of ultrasonic velocities obtained by ultrasonic measurements. Level of degradation of the samples was monitored before and during testing using Image Pro Plus program for image analysis. The capability of non-destructive test methods such are: ultrasonic velocity technique and image analysis for simple, and reliable non-destructive methods of characterization were presented in this investigation.
