Thermodynamic Optimization and Calculation of the EuCl3-CaCl2 Binary System
【摘要】 引入短程有序—扩展似化学模型来描述EuCl3-CaCl2二元体系液相的Gibbs自由能,根据实验测定的相图和混合焓数据,运用CALPHAD技术对该体系进行了热力学优化和计算,优化计算的结果和实测值符合很好.
【Abstract】 In this paper,the Gibbs energy of liquid phases in the EuCl3-CaCl2 system was described by the new modified quasi-chemical model in the pair approximation for local order.Based on measured phase equilibrium data and experimental enthalpies of mixing of the binary system,a set of thermodynamic functions have been optimized by using the CALPHAD technique.The calculations show good agreement with experimental phase diagrams and thermodynamic values.
