至今只见到某些稀土氯化物二元相图的报道,而含稀土的三元熔盐体系相图则研究甚少。据报道,CeCl_3-CaCl_2-MgCl_2体系中相关的三个二元体系均属简单低共熔型。曾重新考察并测定其低共熔点的组成与温度为:CeCl_3-MgCl_2,54.0wt.％CeCl_3(660℃);CeCl_3-CaCl_2,57.0 So far only to see some rare earth chloride binary phase diagram of the report, and rare earth-containing ternary molten salt system phase diagram research rarely. It is reported that the three binary systems related to CeCl_3-CaCl_2-MgCl_2 are all simple eutectics. Have re-examined and measured the composition and temperature of its eutectic point: CeCl_3-MgCl_2, 54.0wt.% CeCl_3 (660 ℃); CeCl_3-CaCl_2, 57.0
