Comparative Thermodynamic Analysis of the Bi-Ga0.1Sb0.9 Section in the Bi-Ga-Sb System

Results of the comparative thermodynamic analysis of the Bi-Ga_0.1Sb_0.9 section in theBi-Ga-Sb system are given in this paper. Experimental calorimetric investigations were done according to Oelsen's method, while for the thermodynamic prediction Chou's general solution model was applied. Activities, activity coefficients, partial molar quantities for bismuth and integral molar quantities were obtained at a temperature of 1073 K. Based on obtained cooling curves, DTA and SEM results for the investigated samples, phase diagram of the investigated section is constructed and presented in this paper, too. This revised version was published online in July 2006 with corrections to the Cover Date.
