Phase equilibria in the Ag-Bi-Te system

Abstract

The Ag-Bi-Te system has been investigated over the whole concentration range using DTA, powder X-ray diffraction, microhardness measurements, and measurements of the emf of concentration cells with reference to Ag/AgCl electrodes. The vertical sections Ag₅Te₃-Bi₂Te₃, AgBiTe₂-Bi(Te) and Ag-Bi₂Te, an isothermal section at 400 K, and liquidus-surface projection have been designed. The fields of crystalline phases, including the ternary compound AgBiTe₂, have been determined.
