The technological conditions for the single crystal growth and manufacturing of ceramic materials from micro- and nanocrystalline powders were developed close to the optimal ones. The particle size distribution of nanocrystalline powders was studied. The features of the microstructure of ceramic materials made from micro- and nanocrystalline powders are considered. The electrical, optical, and mechanical parameters of single crystals and ceramics (with different values of average crystallite sizes) based on Ag7+x(P1-xGex)S6 solid solutions were measured. The mechanism of formation of solid solutions and the effect of disorder of the crystal structure on the change of electrical and optical parameters have been determined. The influence of structural and microstructural features of ceramic materials on changes in their electrical and mechanical parameters is explained and substantiated. As a result, the most technologically advanced materials suitable for possible use as working elements of solid-state energy sources were found  Product Description popup.authors Babuka Tetiana Ya.
