Abstract
The present invention pertains to a method for removing a substance (X) from a solid metal or semi-metal compound (M X) by electrolysis in a melt of M Y, which comprises conducting the electrolysis under conditions such that reaction of X rather than M deposition occurs at a electrode surface, and that X dissolves in the electrolyte M Y. The substance X is either removed from the surface (i.e., M X) or by means of diffusion extracted from the case material. The temperature of the fused salt is chosen below the melting temperature of the metal M . The potential is chosen below the decomposition potential of the electrolyte.
