Abstract

PURPOSE:To efficiently remove a coating metal from the metal oxide base material by heating a material obtd. by coating the base material with the metal and by feeding gaseous chlorine to volatilize the coating metal as chloride. CONSTITUTION:A material 1 obtd. by coating the metal oxide base material with a metal is set on material holders 2 and put in a chlorination vessel 3 so that the contact of the material 1 with gaseous chlorine is accelerated. The vessel 3 is heated with a circular electric furnace 5 and gaseous chlorine is fed from a feed pipe 4 to volatilize the coating metal as chloride. The volatilized chloride is removed from the system through an exhaust pipe 6 so heated that the chloride does not condense. The coating metal can be removed at a high removal rate and the base material can be reutilized because the surface roughness is not considerably changed.
