一、前言 熔盐电解是生产混合稀土金属和镧、铈、镨等金属的简便而经济的方法,为世界各国广泛采用。 我国从五十年代后期,在开发稀土资源的同时,开始了熔盐电解制取混合稀土金属和镧、铈、镨的研究,六十年代末从事熔盐电解稀土有色金属中间合金的研究,近年来
First, the introduction Molten salt electrolysis is the production of rare earth metals and lanthanum, cerium, praseodymium and other metals in a simple and economical way, widely used in all countries in the world. From the late 1950s, while developing rare earth resources, the research on mixed rare earth metals and lanthanum, cerium and praseodymium in molten salt electrolysis began to be studied. In the late 1960s, the research on the rare earth nonferrous metal intermediate alloys was carried out by molten salt electrolysis. In recent years, Come
