Using complex methods of physical and chemical studies: differential thermal (DTA), x-ray diffraction (XRD), microstructural (MA) analyzes, as well as by measuring mikrohardness and density the nature of the interaction in the Dy2 Te3 -PbTe system was studied an a state diagram was constructed. The temperature dependence of electrical conductivity and thermo EMF was studied system alloys. It has been established that when, Dy2 Te 3 is introduced into the PbTe composition, solid solutions are formed and some physicochemical properties change. The formation of compounds of the composition Dy2 PbTe 4 and Dy2 Pb4 Te 7 is also observed in the system.
