摘要
借助DTA研究了LaCl_3-MgCl_2-LiCl三元体系的液相限,发现本体系内有对应于LaCl_3和α-固溶体(MgCl_2,LiCl)的两个液相面,一条二次结晶线和它的一个最低点M(63.8wt-%LaCl_3,2.0wt-%MgCl_2,34.2wt-%LiCl;492℃),结合液相限的测定,初步探讨了LnCl_3-MgCl_2-LiCl体系(Ln=La,Ce,Pr及Nd)相图中的某些变化规律。
Two surfaces corresponding to LaCl_3 and α-solid solution (MgCl_2, LiCl)
respectively, and one secondary crystallization curve with a minimum M at 63.8
wt-%LaCl_3, 2.0wt-%MgCl_2, 34.2 wt-%LiCl; 492℃ were found by means of DTA. In
combination with liquidus determination, an approach was also made to the alteration in
LnCl_3-MgCl_2-LiCl system, where Ln denotes La, Ce, Pr or Nd.
