稀土合金的制备方法有熔炼法、金属热还原法和熔盐电解法。与前两种方法相比，熔盐电解法具有生产成本低、稀土合金成分均匀、易于控制、稀土合金质量好等优点。稀土合金可以在工业规模上容易地和连续地制备。从稀土合金在结构材料、磁性材料和储氢材料等方面的应用出发，综述了熔盐电解法制备镁、铝、铁、钴、镍、铜等稀土合金的研究进展。最后对今后的研究工作进行了展望。
Rare earth alloys can be prepared through the methods of melting, metallothermic reduction, and molten salt electrolysis. Compared to the former two methods, the molten salt electrolysis method has several advantages: the production cost is lower, the composition of the rare earth alloys is uniform and easy control, and the quality of the rare earth alloys is good. The rare earth alloys can be prepared easily and continuously on industrial scale. In this paper, the research progress in the molten salt electrolysis preparation of the rare earth alloys of magnesium, aluminum, iron, cobalt, nickel, and copper is reviewed by considering the rare earth alloy applications in structural, magnetic, and hydrogen storage materials. The prospects of the related research works are discussed.
