AB  - This research describes a study of 11 selected samples of brick clays applied in roofing tile production, by using simultaneous thermal analysis. Additionally, the laboratory-sized samples were prepared and fired (850-950 °C) and technological properties were determined. Mathematical analysis was applied to sum all the experimental results and help discriminate the samples by their behavior during firing. The samples, very similar according to mineralogical and chemical content, as well as granulometry tests, were successfully grouped using principal component analysis (PCA). The PCA was used to explore and easily visualize the differences between samples. The PCA performed for differential thermal analysis (DTA), differential scanning calorimetry (DSC) and differential thermogravimetry (DTG) curves clearly showed that the heat flow was mainly influenced by carbonate content and its grain size, while DTG discriminated samples according to the contents of clay minerals and carbonates. In addition, dilatometry analysis revealed which samples underwent the highest densification during the firing process. The PCA analysis of fired products properties showed that the highest correlations were between water absorption with firing shrinkage and compressive strength.

AB  - Coordination chemistry provides the know-how for the synthesis of the
precursor compounds with variable composition and structures, while the thermal
induced changes may control the crystalline structure, phase composition,
morphology, size, texture, and other properties of their pyrolytic products [1]. In
terms of coordination chemistry and thermal analysis, our research has been focused
on the synthesis of mixed ligand complexes [2] that can be used as precursors for
obtaining diverse (compositional and structural) oxides, depending on their
thermoreactivity.
The main goal of this approach was the reduction of the temperature at which
the oxides are formed (up to 600–700 °C) comparative to the standard ceramic
methods. The effect of the different atmospheres (dynamic air or N2) on the thermal
decomposition of Zn benzenedicarboxylate complexes with 2,2’-dipyridylamine was
investigated. The formation of ZnO nanopowders was identified using XRPD and
FESEM techniques. The influence of the adopted architecture of ternary metal
complexes used as templates for ZnO nanopowders was discussed. The thermal
decomposition kinetics of precursors was studied under non-isothermal conditions.
In addition, the antibacterial activity of obtained ZnO nanopowders was also
analyzed.

AB  - The aim of this study was to test montmorillonite and hydromica type of brick clays by using simultaneous thermal analysis and dilatometry in an assessment of the suitability of brick clays to produce building elements. The plasticity coefficient and drying susceptibility were determined to discover the behavior of brick clays. Fired products' characteristics were studied by performing water absorption and compressive strength tests. All the methods were employed in the construction of the firing curves in a tunnel kiln. The results could increase the degree of certainty to lead the production process towards obtaining the desired features of brick elements.

AB  - The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center dot 6H(2)O and CeCl3 center dot 7H(2)O, and two cerium (IV) salts, i.e., Ce (SO4)(2)center dot 4H(2)O and (NH4)(2)Ce(NO3)(6) were applied. The proposed procedures for the CeO2 preparations were realizdd using the same hydrothermal treatment conditions. The products were characterized using X-ray powder diffraction (XRD) and thermogravimetric (TG) analysis, and the morphology was determined using scanning (SEM) and transmission electron microscopy (TEM). The spectral properties of the obtained nanopowders were characterized by FT-IR, Raman scattering and UV-vis spectroscopy. The results revealed the influence of the precursors on the crystallinity, crystallite size, band gap energy, morphology and purity of the synthesized samples.
