| Abstract: | The utilization of magnesium and rare earth resources in China,and the preparation of metal magnesium and rare earth-magnesium alloys by molten salt electrolysis method were briefly summarized.The possible problems and related technical problems in the electrolytic preparation of rare earth-magnesium alloys using incomplete dehydrated magnesium chloride were reviewed.The negative effects of water and the hydrolytic products of metal chlorides on the electrolytic process and their solution were analyzed.The transformation reactions between metal chlorides and metal oxides during electrolysis in the molten salts,the electrolyte composition,the methods of adding raw materials for the electrolysis,the design of the electrolytic cell,and the purification of the electrolytic gas were discussed comprehensively. |
