The invention provides a preparation method of magnesia-cerium alloy. The method includes the following steps: preparing metal magnesium and cerium salts according to the mass ratio of magnesium to cerium in the desired magnesium-cerium alloy; Magnesia-cerium alloy was prepared by molten salt electrolytic diffusion method using magnesium as liquid cathode. In the process of electrolytic diffusion, the ratio of Faraday energy required to control the discharge of cerium ion in cerium salt and electrolytic energy of cerium salt is 1:1~1.4. Using the above preparation method, through the molten salt electrolytic diffusion method, magnesium metal as the liquid cathode, during the electrolytic process to control the cerium ion discharge in cerium salt and cerium salt electrolytic battery required by the matching consistency between the Faraday quantity and the cerium salt electrolytic quantity, the electric ratio of the two is controlled from 1:1 to 1.4, which can make the content of two metal components in magnesium-cerium alloy products basically consistent with the target content, from To achieve effective control of alloy composition. And through the molten salt electrolytic diffusion method, the invention prepares magnesia-cerium alloy.
