The results of studying the temperature-induced polymorphic phase transformations in Cu{sub 1.50}Zn{sub 0.30}Te and Cu{sub 1.75}Cd{sub 0.05}Te single crystals are presented. The single crystals have been investigated in the range of 290–1100 K using X-ray diffraction analysis. The temperature dependences of the unit-cell parameters, X-ray density, and coefficients of thermal expansion for each polymorphic modification of Cu{sub 1.50}Zn{sub 0.30}Te and Cu{sub 1.75}Cd{sub 0.05}Te single crystals are presented. The influence of cationic substitution (replacement of Cu{sup 2+} with Zn{sup 2+} and Cd{sup 2+} cations) on the phase-formation processes, number of polymorphic modifications, and temperature of structural phase transition in single crystals of these solid solutions is demonstrated.
