摘要
基于CALPHAD方法对MNO3-Ca(NO3)2(M=Li,Na,K)二元相图的试验数据首次进行了热力学优化拟合,得到了3个二元相图的过量混合热力学性质的参数及Ca(NO3)2的熔化吉布斯自由能随温度变化的函数表达式,并用拟合的参数计算了3个二元相图,最后将计算得到的相图与试验相图进行了比较。
Melting Gibbbs energy of Ca（NO3 ）2 and a consistent set of thermodynamic parameters were optimized by CALPHAD method for MNO3-Ca（NO3）2 （M= Li, Na, K） binary system, which was for the first time thermo-dynamically assessed. Phase diagrams of MNO3-Ca （NO3）2 （M = Li, Na, K） binary system were calculated with the model parameters obtained in this study. Comparison of calculated and experimental phase diagram data was carried out.
