摘要: 研究稀土熔盐相图对于了解稀土化合物的基本物理化学性质,从已知相图提取热力学数据,探讨相图规律和开发固体配合物具有重要意义.但迄今稀土熔盐相图报道不多[1-3],三元相图更少.本文测定了未见文献报道的ErCI3-MgC12-LiCI三元体系相图.

Abstract: The liquidus of ErCl3-MgCl2- LiCl ternary system has been investigated by meansof DTA.It was found that there are five surfaces correspending to the primary crystallizationof ErCl3、Li3ErCl6、α、α1、α2 respectively,and six univariant lines related to the secondary crys-tallization in the esystem, The eutectic point is at 446℃(65.0% ErCl3,18.5% MgCl2,16.5% LiCl)and the peritectic point is at 470℃(56.0% ErCl3,23.0% MgCl2,21.0% LiCl).

Key words: ErCl3, ErCl3-MgCl2-LiCl ternary system, phase diagram
