Abstract

The Bi₂Te₃-Er₂Te₃ section of the Er-Bi-Te ternary system was investigated by the methods of differential thermal, X-ray phase and microstructural analyzes and also by measuring the microhardness and density. In the system, a ternary compound of the composition ErBiTe₃is formed, which crystallizes in a hexagonal lattice with the following parameters: a = 4,20; c = 31,11Å (c / a = 7,1) The solubility on the side of Bi₂Te₃ is 6 mol% at room temperature. The electrophysical properties of ErBiTe₃ compounds have been studied.
