随着金属钐在磁性材料及有色金属的广泛应用，金属钐的低成本制备已成为人们关注的热点。本项目结合电化学研究、过程动力学研究和熔盐结构研究，在铝液态阴极法制备铝钐合金成熟工艺的基础上，通过研究电解过程的过程动力学、钐离子的电化学变化、单质钐的存在与稳定性以及熔盐中离子浓度的变化等，来探索熔盐电解法制备金属钐及其合金的可能性及工艺。其主要成果可用于指导熔盐体系和其他变价稀土元素电解制备的研究，可大幅降低金属钐的生产成本和能源消耗，为钐合金的大规模生产奠定基础。

With the extensive application of samarium metal in the magnetic materials and nonferrous metal, the low-cost production of samarium has become the focus of attention. Uniting the study of melton structure, electrode kinetics and electrochemistry, the project will probe the probability and technology of electrochemical preparation of samarium and its alloys on the mature technology of Al-Sm alloys by liquid cathode of aluminum. The major achievements of the project can be used for guiding the research of molten salt systems and electrolytic preparation of other rare earth, and greatly reduce production costs and energy consumption, and lay the foundation for the large-scale production of samarium alloys.
