Different Approach to Thermodynamic Description of Bi-Te Binary System

Abstract The aim this work was the reinvestigation of phase equilibria in Bi-Te system. as-cast and long-time equilibrated alloys binary system were analysed by scanning electron microscopy, X-ray diffraction (XRD) differential thermal analysis (DTA) methods. primary solidified phases identified for samples. existence four intermetallic phases: Bi 2 Te 3 , BiTe, Te, 7 confirmed. Three them melt incongruently peritectic reactions. model parameters all assessed optimization using available data Calphad method. stabilisation these other ternary systems discussed taking into consideration its future application thermodynamic description Ag-Bi-Te
