1. In a carbochlorination process for the production of volatile metal chlorides wherein chlorine gas contacts zirconium oxides in a reaction zone in the presence of carbon at elevated temperatures and builds up a carbochlorination residue containing carbon in the reaction zone, the improvement comprising reducing the volume of the carbochlorination residue in the reaction zone by periodically introducing, after the build up of a carbochlorination residue in the reaction zone, zirconium oxide or zircon into the reaction zone without introducing any carbon, to thereby react the carbon in the carbochlorination residue with the zirconium oxide or zircon.
