运用CALPHAD(相图计算)技术对LiBr—SrBr2二元体系进行优化和计算,计算得到的共晶点为34．93％(摩尔百分比) SrBr2,709．20 K,化合物LiSr2Br5的转熔温度和组成分别为760．00 K和55．43％(摩尔百分比)SrBr2．从LiBr—SrBr2体系的实验数据出发,预报了该体系液相混合焓和混合熵,计算得到的结果与实验相图和热力学数据相吻合．
The LiBr-SrBr2 binary system was optimized and calculated by CALPHAD (phase diagram calculation). The calculated eutectic point is 34.93% (mole percent) SrBr2, 709.20 K, the transition temperature and composition of LiSr2Br5 Respectively 760.00 K and 55.43% (mole percent) SrBr2. Based on the experimental data of LiBr-SrBr2 system, the enthalpy and entropy of mixture in liquid phase are predicted. The calculated results agree well with experimental phase diagram and thermodynamic data.
