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
