METHOD FOR SMELTING METALLIC TITANIUM

摘要

PROBLEM TO BE SOLVED: To provide a method for smelting metallic titanium, in which titanium oxide is reduced by forming an electrolytic bath of an inorganic molten salt in a reaction vessel and by utilizing an electrolysis method and the elution of impurities such as metal impurities, from the wall surface of the reaction vessel and the damage on the reaction vessel itself are eliminated and which is advantageously operative on an industrial scale. SOLUTION: The method for smelting the metallic titanium comprises a step of forming a solidification layer of the inorganic molten salt on the inner wall surface of the reaction vessel and a step of balancing the quantity of heat generated as a result of electrolysis by the solidification layer and inputted to the electrolytic bath and the quantity of the heat emitted to the outside of the reaction vessel from the electrolytic bath through the solidification layer and the wall surface of the reaction vessel.
