Abstract

The interaction in the quasi-ternary system Sb₂Se₃-CuTe-Cr₂Te₃ along the Sb₂Se₃-CuCr₂Te₄ section was studied by methods of physicochemical analysis: differential thermal (DTA), X-ray phase (XRD), microstructure (MSA), as well as by measuring the density and its microhardness and plotted. The phase diagram of the system is quasi-binary, eutectic type. The composition of the double eutectic formed in the system is 20 mol % CuCr₂Te₄and a temperature of 490°C. As a result of the analysis of the microstructure, it was determined that there are single-phase fields based on the original components. It was found that at room temperature, solid solutions based on Sb₂Se₃ extend to 5 mol % CuCr₂Te₄, and on the basis of CuCr₂Te₄ solid solutions reach 13 mol % Sb₂Se₃.
