Using Al rod as anode, electrochemical formation of Sm-Al alloy on Mo electrode from Sm2O3 in LiCl-KCl-MgCl2-KF molten salts was investigated. Samarium mainly exists in the form of Al2 Sm in Li-Mg matrix, and the concentration of Sm in this alloy runs up to be as high as 34.7%. The reaction of samarium preparation appears like a replacement reaction. The new preparation method makes possible a high samarium content in electrochemical deposition of Sm-Al alloy. Using Al rod as anode consumedly decreased the electrolytic cell voltage, and facilitated Sm deposition from Sm2O3 . This preparation method uses Sm2O3 as raw materials to gain samarium alloy directly, which could revolutionize the industrial production of samarium alloys. 关键词：熔盐电化学制备方法 Al合金钼电极氯化锂氯化钾氯化镁 SM2O3
