The phase transitions and thermal expansion of apatite-structured compounds with the general formula MII5(AVO4)3L (MII = Ca, Sr, Cd, Ba, Pb; AV = P, V, Cr, Mn; L = OH, F, Cl, Br, I) have been studied by high-temperature X-ray diffraction and differential thermal analysis. Polymorphic transition nature was explained on the basis of the structure data. Connection between thermal stability and peculiarities of thermal expansion, which were explained in assumption of composition and structure of apatites was ascertained.

Inorganic Cr- and Mn-containing pigments of different structural types were investigated by hightemperature and spectroscopic methods. The differential scanning calorimetry in the temperature interval 298e1723 K was applied to measure temperatures of phase transition and melting of the studied compounds. High-temperature X-ray diffraction in the range 298e1173 K was used for the determination of the thermal expansion coefficients for the first time. Factor group analysis was used to predict general vibration modes of pigments and determine the activity of these vibrations in Raman and IR spectra, the Assignment of bands in Raman, IR and diffuse reflectance spectra was undertaken.

Aluminium matrix composites containing a high volume fraction of silicon carbide particulates were produced by the pressureless infiltration technique. The metal matrix composites thus obtained were characterized for phase composition, microstructure, density, porosity and coefficients of thermal expansion. All composites were studied in their as-prepared condition without any further heat treatment. Behaviour of bulk properties such as thermal expansion and density was studied as a function of the volume fraction of silicon carbide within the volume fraction range 0.41–0.67. The coefficients of thermal expansion of the composites were found to vary between 14 × 10−6 and 7 × 10−6 K−1 in a non-linear fashion as a function of the volume fraction of SiC. The variation in the density of the composites was found to be linear with volume fraction in the usual manner. The results obtained were compared with existing models on the behaviour of macroscopic properties of composite materials
