通过基于最小二乘法的计算机程序 THERMO-CALC，使用各个相的吉布斯能量模型，从实验热力学和相图数据中获得了 Ag-Ce 系统的优化热力学描述。 Ag-Ce 体系含有四种金属间化合物。计算出AgCe、Ag2Ce、Ag51Ce14和Ag4Ce的标准生成焓分别为-22.331、-20.194、-18.998、-17.863 kJ/mol。计算值与实验数据吻合较好
An optimized thermodynamic description of the Ag–Ce system has been obtained from experimental thermodynamic and phase diagram data by means of the computer program THERMO-CALC based on the least-squares method, using models for the Gibbs energy of individual phases. The Ag–Ce system contains four intermetallic compounds. The calculated standard enthalpies of formation of AgCe, Ag2Ce, Ag51Ce14and Ag4Ce are −22.331, −20.194, −18.998, −17.863 kJ/mol, respectively. The calculated values and experimental data are in good agreement
