Abstract:
A method for preparing rare earth alloys by molten salt electrolysis using rare earth oxides as the raw material is provided, where the electrolytic cell used is divided into the anode chamber and the cathode chamber containing melts such as anolyte, catholyte and liquid alloy. The method has the advantages of continuous production, high operability, low requirements on raw material purity and high quality of rare earth alloy products.
