Qısa məlumat

Alloys of the As2Se3-CuCr2Te4 system were synthesized in a wide range of concentrations, and their physico-chemical properties were studied by differential thermal analysis (DTA), X-ray diffraction (XRD), microstructural (MSA) analysis, as well as by determining the microhardness and density, and its T-x phase diagram was constructed. It has been established that the phase diagram of the As2Se3-CuCr2Te4 system is quasi-binary of the eutectic type. The system has small single-phase fields based on the original components. In the As2Se3-CuCr2Te4 system, the area of the solid solution based on the As2Se3 compound at room-temperature is 2 mol%, and the area of the solid solution based on the CuCr2Te4 compound is 6 mol%. Joint crystallization of As2Se3 and CuCr2Te4 ends at the double eutectic point with a composition of 15 mol% CuCr2Te4. With slow cooling in the As2Se3-CuCr2Te4 system based on As2Se3, the glass formation region reaches 10 mol% CuCr2Te4. The magnetic properties of the obtained solid solutions (CuCr(2)Te4)1-x(As(2)Se3)(x) (x-0.03; 0.05) were studied.
