THE TLPbTe3-TbGdTe6-TbBiTe6 ISOPLETH SECTION OF THE Tl-Pb-Bi-Gd-Te SYSTEM
The purpose of this study was to investigate the phase relations in the Tl-Pb-Gd-Te quaternary system on the Tl9GdTe6-Tl9BiTe6-Tl4PbTe3 composition area. Based on the results of the differential thermal analysis, the powder X-ray diffraction technique and the microhardness measurements, it revealed that the system is characterized by unlimited solid solutions crystallized in Tl5Te3 structure type.
