Abstract:The possibility of separating RE-carbide by electrolysis was discussed on the basis of electrolyte contrast, magnetic separation and X-ray diffraction analysis. The experiments showed that the electrolyte consisting of 1℃ LiCl + 5%N(CH₂CH₂OH)₃+5%C₂H₆O₂+89% anhydrous CH₃CH₂OH was appropriate for the electrolytic separation of Ce-carbide and Fe-Ce-carbide. And it was found that when the content of cerium in the steel exceeded a certain amount, Fe₂Ce₂C₃ and Ce₂C₃ would be formed in sequence with the increase of the content of carbon.

Key words: Ce-carbide; Fe-Ce-carbide; electrolytic separation;
