Qısa məlumat

Ternary system Tl-Er-Te was experimentally investigated in the Tl2Te-Tl5Te3-Tl9ErTe6 compositions area by methods of differential thermal analysis, powder X-ray diffraction technique and microhardness measurements applied to equilibrated alloys. Based on the experimental data, some isopleth sections and isothermal section at 300 K, as well as projections of the liquidus and solidus surfaces, were constructed. It was shown that more than 90% of the concentration triangle is occupied by the homogeneity area of solid solutions with Tl5Te3 structure (δ-phase). A narrow area of solid solutions (α-phase) based on Tl2Te was detected. α-and δ-phases are separated by α+δ two-phase area.
