THE INFLUENCE OF ELEMENT Pr ON PHYSICO-CHEMICAL PROPERTIES OF SOLID SOLUTION (Sb₂Te₃+Bi₂Te₃+Se+Te) of “p”-TYPE

The phase microdiagram of the (Sb₂Te₃+Bi₂Te₃+Se+Te)_1-х(Pr)_х system has been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, and microhardness and density measurements. The influence of Pr element on physico-chemical properties of solid solution (Sb₂Te₃+Bi₂Te₃+Se+Te) of “p”-type analysed. At room temperature, the
(Sb₂Te₃+Bi₂Te₃+Se+Te) based solid solution extends to 4 at. % Pr
