PROCESS FOR PRODUCING Ti THROUGH Ca REDUCTION AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2006/049050

Kind Code:

A1

Abstract:

A process for producing Ti through Ca reduction, comprising providing an apparatus including a reaction vessel for retaining a molten salt containing CaCl₂ and having Ca dissolved therein, an electrolytic vessel for retaining a molten salt containing CaCl₂ and continuous means capable of moving while having parts thereof dipped in the molten salts of the reaction vessel and electrolytic vessel; conducting electrolysis of the molten salt of the electrolytic vessel to thereby form Ca on the negative electrode side, the formed Ca deposited on and attached to the continuous means; transporting the Ca to the reaction vessel; and feeding TiCl₄ into the reaction vessel to thereby form Ti. This process is economically advantageous as the feeding rate of TiCl₄as a raw material can be increased, as continuous production can be effected, and as Ca consumed by reduction reaction of TiCl₄can be replenished by electrolysis of CaCl₂. Thus, this process can be effectively utilized as means for efficient economically advantageous production of high-purity metallic Ti and can find wide applications.
