Abstract
Two-phase alloys Bi8Te9+Bi4Te5and BiTe+Bi8Te9were studied by the electromotive forces method (EMF) in the temperature range 300 - 450 K. From the EMF data, the relative partial molar functions of bismuth in the alloys were calculated. The potential-forming reactions responsible for these partial functions were compiled, the values of the standard thermodynamic functions of formation, and the standard entropies of Bi8Te9and BiTe compounds were calculated. A comparative analysis of the data for BiTe with the literature data was carried out; for Bi8Te9, the thermodynamic functions were obtained for the first time.
