本文介绍了Ga-Sb-Pb三元系的热力学预测方法。计算中采用了周通解模型与传统的科勒模型和Toop模型进行了比较和讨论。积分混合焓和积分过剩吉布斯能对组成的15个调查截面在973 K和1073 K，分别获得根据应用模型。三种模型的计算结果比较表明，三者之间具有较好的一致性。所得结果用于进一步计算所研究的三元体系中各组分的偏摩尔量。所有组分在1073 K下的计算活度值以等活度图的形式给出。(C)2004爱思唯尔有限公司保留所有权利。
The results of some thermodynamic prediction methods applied to the Ga-Sb-Pb ternary system are presented in this paper. The Chou general solution model and the traditional models of Kohler and Toop were included in the calculation for the comparison and discussion. Integral enthalpy of mixing and integral excess Gibbs energy dependences on composition for the 15 investigated cross sections at 973 K and 1073 K, respectively, were obtained according to the applied models. The comparison between the results of the three models shows good mutual agreement. Obtained results were used for the further calculation of partial molar quantities for every component of the investigated ternary system. Calculated activity values at 1073 K for all components are given in the form of isoactivity diagrams. (C) 2004 Elsevier Ltd. All rights reserved.
