FeS-PbS和PbS-ZnS二元系的热力学优化

Thermodynamic Optimization of FeS PbS and PbS ZnS Binary Systems

采用ＲｅｄｌｉｃｈＫｉｓｔｅｒ多项式描述体系液相的过剩自由焓，根据试验相图和已知的热力学数据优化得到了ＦｅＳＰｂＳ和ＰｂＳＺｎＳ二元系的热力学参数。用优化结果计算的相图与试验测量值吻合较好。

The phase diagrams and thermodynamic properties of the FeS PbS and PbS ZnS binary systems are optimized based on available experimental data. The Redlich Kister polynomial is used to describe the excess Gibbs energies of liquid phases in these systems. The calculated phase diagrams based on the optimized parameters are in good agreement with the experimental data.
