SYNTHESIS OF ALLOYS OF THE Sb2Se3-CuCr2Te4 SYSTEM AND PHYSICO-CHEMICAL PROPERTIES

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 % CuCr2Te4 and 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.

SYNTHESIS AND PHYSICO-CHEMICAL INVESTIGATION OF ALLOYS OF THE Sb2S3–Cu2Cr4Te7 SYSTEM

“…Based on the foregoing, the study of the interaction of antimony chalcogenides with Cu 2 Cr 4 Te 7 compounds is relevant, having scientific and practical significance. Previously, we studied systems consis-ting of antimony and chromium chalcogenides [17][18][19][20][21].…”
