To study the nature of the interaction between Sb2S3 and Cu2Cr4Te7 compounds, alloys were synthesized in a wide range of concentrations and studied using physicochemical analysis (DTA, XRD, MSA, as well as measurements of density and microhardness) and a phase diagram was constructed. The state diagram of the system is partially quasi-binary, with the formation of eutectic equilibrium and peritectic transformation. The regions of homogeneity in the Sb2S3–Cu2Cr4Te7 system were determined from the initial components. In a system based on the Sb2S3 compound, solid solutions reach up to 4 mol % Cu2Cr4Te7, and solid solutions based on Cu2Cr4Te7 – up to 10 mol % Sb2S3 at room temperature. The temperature dependence of electrical conductivity and thermo-emf has been studied. 1, 2 and 4 mol % Cu2Cr4Te7 solid solutions of alloys of the Sb2S3–Cu2Cr4Te7 system in the temperature range of 20–2500C
