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
