熔盐体系相图,对于研究熔盐体系的各种物理化学性质及电解制备金属是非常必要的.LaCl_3-BaCl_2-LiCl三元相图尚未见文献报道,因实际工作需要本文测定了本三元体系相图.其相关的二元体系相图,文献均有报道.LaCl_3-LiCl与BaCl_2-LiCl体系均属简单低共熔体系.前者e(65.8wt%LaCl_3,508℃),后者认为e(13.3Wt.%BaCl_2,512℃),作者重新考察其结果为e(13.3wt.%BaCl_2,520℃).LaCl_3-BaCl_2体系,Vogel报道该体系有一化合物Ba_2LaCl_7,属固液异组成相图类型,无变点分别为e(70.0wt.%LaCl_3,730℃),P
The phase diagram of molten salt system is very necessary for the study of various physico-chemical properties of molten salt system and electrolysis for metal preparation.The ternary phase diagram of LaCl_3-BaCl_2-LiCl has not been reported in the literature, The phase diagram of the binary system, the literature have been reported.LaCl_3-LiCl and BaCl_2-LiCl system are simple eutectic system.The former e (65.8wt% LaCl_3,508 ℃), the latter that e (13.3wt.% BaCl_2, 520 ℃) .LaCl_3-BaCl_2 system, Vogel reported that the system has a compound Ba_2LaCl_7, which belongs to the solid-liquid heterogeneous phase diagram type , No change points were e (70.0wt.% LaCl_3,730 ℃), P
