本文研究了混合稀土氯化物与氯化钾体系在石墨、金属钨、钼上的润湿性,采用光学座滴法测定了它们之间的湿润角(θ°)。并对所得数据步行了分析与探讨。为电解RECl_3-KCl熔盐制取稀土金属提供了基础数据。
In this paper, the wettability of mixed rare earth chloride and potassium chloride systems on graphite, tungsten and molybdenum was studied. The wetting angle (θ °) between them was measured by optical droplet method. And walked the analysis and discussion of the data obtained. It provides basic data for the electrolysis of RECl_3-KCl molten salt to prepare rare earth metal.
