SYNTHESIS AND PHYSICAL-CHEMICAL STUDY OF COMPOSITE MATERIALS IN THE TlАs<subscript>2</subscript>Se<subscript>4</subscript>-CuCr<subscript>2</subscript>Te<subscript>4</subscript> SYSTEM.

In the TlАs2Se4-CuCr2Te4 system, samples were synthesized in a wide range and studied by methods of physical and chemical analysis: differential thermal analysis (DTA), X-ray diffraction analysis (XRD), microstructural analysis (MSA), as well as determination of density and microhardness and its was constructed T-x phase diagram. It has been established that the phase diagram of the TlАs 2Se4-CuCr2Te4 system is quasi-binary and eutectic. The composition of the eutectic formed between the compounds ТlАs2Se4 and CuCr2Te4 is 10 mol % CuCr2Te4, temperature 498 K. At room temperature, solid solutions based on TlAs2Se4 in the system reach 3 mol. % CuCr2Te4, and based on CuCr2Te4 - 7 mol % TlAs2Ce4. Under normal conditions, the glass transition region based on CuCr2Te4 extends to 12 mol % TlAs2Se4. [ABSTRACT FROM AUTHOR]
