研究熔盐体系的各种物理化学性质及电解制备金属, 相图是非常必要的。由于稀土元素分离提纯及实验时测定相图的困难, 至今只能见到某些稀土氯化物的二元相图, 而含稀土的三元氯化物体系相图的报导甚少, NdCl3-BaCl2-LiCl三元相图尚未见到文献报导, 本文测定了该三元体系的相

The phase diagram of ternary system NdCl3-BaCl2-LiCl was investigated by means of DTA and x-ray diffraction anal. There are 5 surfaces corresponding to the primary crystallization of NdCl3, a-BaCl2, b-BaCl2, LiCl and Ba3NdCl9 resp., and 6 univariant lines related to the secondary crystallization in this system. A compound, formed in the solid state, was found. The temperature of decomposition is at 427癈.
