Abstract
The interaction in the section Cu2Cr4Te7-Te of the quasi-ternary system Cu2Te-Cr2Te3-Te was studied by physicochemical analysis methods (differential thermal, X-ray powder diffraction, and microstructural analyses) and also by analyzing the temperature dependences of the specific magnetization of samples. In the section, there is a wide region of homogeneity of solid solutions based on Cu2Cr4Te7, which extends at room temperature to 42 at %, and there are also regions of crystallization of two more ternary tellurides, Cu4Cr8Te17 and CuCr2Te5. The characteristics of the formation and melting of the obtained phases were found. The Curie temperatures of the solid solutions based on Cu2Cr4Te7 are 285–325 K, and those of Cu4Cr8Te17 and CuCr2Te5 are 270 and 190 K, respectively.
