Abstract

Abstract: This work presents a new method for preparation of samarium alloy. 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 Al₂Sm 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.

Key words: Electrochemical formation, Molten salt, Sm-Al alloy, Inert electrode
