摘要
The phase diagram of ternary system ErCl_3-CaCl_2-MgCl_2 has been investigated be means of differentialthermal analysis (DTA). It was found that there were three surfaces corresponding to the primary crystalliza-tion of ErCl_3, CaCl_2 and MgCl_2 respectively, three univariant curves related to the a seondary crystallizationand a ternary eutectic point E (67. 8 wt% ErCl_3, 17. 2 wt% CaCl_2, 15. 0 wt% MgCl_2. 524°C ) in the systemErCl_3-CaCl_2-MgCl_2.
