摘要
CeCl_3-MgCl_2-LiCl三元体系中的三个二元体系相图均已有文献报导.其中CeCl_3-LiCl及CeCl_3-MgCl_2都是简单低共熔型的,低共熔点的组成和温度分别为67.0wt%CeCl_3(466℃)和54.0wt％CeCl_3(660℃).MgCl_2则是有最低点M的连续固溶体型,M的组成和温度为59.9wt%MgCl_2(570℃).本文中的二元体系,经验证后直接引用文献数据.据此测定了该三元体系的液相限.共测定七个多温截面.各截面端点组成见表1(Table 1).
The liquidus of ternary system CcCl3-MgCl2-LiCl has been investigated by means of DTA. It was found that there arc 2 surfaces corresponding to the primary crystallization of CcCl3 and phase (solid solution of MgCl2 and LiCl) respectively, and a univariant cruvc with a minimum M (63.5 wt% GcCl3, 2.2 wt% MgCl2; 463℃ ), related to the secondary crystallization in this system.
