Comparative thermodynamic investigation of the Bi-GaSb system

Results of the thermodynamic investigations in the Bi-GaSb system are prese nted in this paper. Thermodynamic characteristics experimentally determined by Oelsen's calorimetric method were compared with values predicted by dif ferent thermodynamic predicting methods (general solution model, Kohler, Mu ggianu, Toop, Hillert) at the temperature of 1073 K. Also, based on the obt ained cooling curves and microstructure analysis of the investigated sample s by optical microscopy, phase diagram of the Bi-GaSb system was investigat ed and compared with literature data.
