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;
