The phase equilibrium of the Sb2Te3-HoTe3 system was studied by means of physical and chemical analysis methods DTA, RFA, MQA, as well as density and microhardness measurements, and its phase diagram was constructed. It has been determined that the Sb2Te3-HoTe3 system is a partial quasi-binary cross section of the ternary Bi-Ho-Te system. The system undergoes a process of eutectic equilibrium and peritectic transformation. In the Sb2Te3-HoTe3 system at room temperature, of the based Sb2Te3 solid solutions extend to 4.5 mol % and of the based HoTe3 solid solutions have practically not been established.
