摘要
根据实验测定的相图,运用CALPHAD技术对ErCl3-CaCl2体系进行了热力学优化和计算.计算出的相图属于简单低共熔型,低共熔点为850.92K,46.0%(摩尔分数)ErCl3,同时优化计算了该体系的液相混合焓和相互作用系数.这些热力学参数对于稀土金属及其合金的冶炼有重要意义.
From measured phase diagram, the system of ErCB-CaC12 was optimized and calculated by the CALPHAD approach. The calculated phase dliagram is eutectic and the eutectic point is 850.92K, 46.0% （mole fraction）ErC13. Enthalpy of mixing in liquid and interaction parameter of mixing enthalpy have been optimized and calculated in the system. These thermodynamic functions are important for fusion of rare-earth metal and their alloy.
