摘要： The invention relates to a method for producing a magnesium-rare earth intermediate alloy, which belongs to the technical field of molten salt electrolytic metallurgical technology. Inside an electrolysis oven, magnesium chloride, lanthanum praseodymium cerium chloride and potassium chloride in a controlled mass ratio of 5:(40-35):(55-60) are formulated as electrolyte composition, and the electrolysis is performed under a temperature of 800-900° C., a cathode current density of 10-30 A/cm2, and a distance between the electrodes of 4 to 8 cm; and the lanthanum praseodymium cerium chloride and the magnesium chloride are added in a mass ratio of 1:1.5-5 during the electrolysis, thus the magnesium-lanthanum praseodymium cerium intermediate alloy is produced. In the electrolysis process, neither metal magnesium nor rare earth metal is used, only the chlorides of rare earths and magnesium are used, and the rare earth ions and the magnesium ions are co-electrodeposited on the cathode, so as to obtain the intermediate alloy having a melting point close to the eutectic temperature of the rare earth and magnesium. The method has the advantages of high operability, simple process and equipment, stable quality of product by mass production, and easy for commercial scale production.
