Abstract

The aim of the present study was to determine the phase relations in the Tl-Pb-Sm-Te quaternary system on the Tl₄PbTe₃-Tl₉SmTe₆composition area. According to the results obtained by the differential thermal analysis, powder X-ray diffraction technique and microhardness measurements, the system is characterized by the formation of unlimited areas of solid solutions which crystallize in the tetragonal Tl₅Te₃structure type. Receive experimental data can be used for choosing the composition of solution-melt for the growth of high-quality crystals of δ- phase which are of interest like thermoelectric materials.
