A process for the reduction of rare earth oxides to rare earth metals

摘要

The invention relates to a method for reduction of rare earth oxides to rare earth metals (34), comprising the steps of, iodieren of a rare earth oxide to a rare earth iodide heating of the rare earth iodide, by means of a melting temperature to a seltenerdiodidschmelze (21), electrolysis of the seltenerdiodidschmelze (21) under deposition of the rare earth metal (34) at an electrode (23).
