PHASE EQUILIBRIUM IN THE As2Te3-Cu2Cr4Te7 SYSTEM
Abstract
The alloys of the As2Te3-Cu2Cr4Te7 system were investigated by methods of physicochemical analyzes (DTA, XRD, MSA, as well as density and microhardness measurements) and its phase diagram was constructed. Studies have shown that the As2Te3-Cu2Cr4Te7 system is a partially quasi-binary section of the As2Te3-Cr2Te3-CuTe quasiternary system. In a system at room temperature based on As2Te3, solid solutions reach 3.5 mol %, and based on the Cu2Cr4Te7 solid solutions reach up to 17 mol %. Eutectic equilibrium and peritectic transformation occur during chemical interactions between As2Te3 and Cu2Cr4Te7 compounds in the system.
