PROCESS FOR PRODUCING Ti THROUGH Ca REDUCTION AND APPARATUS THEREFOR

摘要

A process for producing Ti through Ca reduction, comprising providing an apparatus including a reaction vessel for retaining a molten salt containing CaCl<SUB>2</SUB> and having Ca dissolved therein, an electrolytic vessel for retaining a molten salt containing CaCl<SUB>2</SUB> 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 TiCl<SUB>4</SUB> into the reaction vessel to thereby form Ti. This process is economically advantageous as the feeding rate of TiCl<SUB>4 </SUB>as a raw material can be increased, as continuous production can be effected, and as Ca consumed by reduction reaction of TiCl<SUB>4 </SUB>can be replenished by electrolysis of CaCl<SUB>2</SUB>. Thus, this process can be effectively utilized as means for efficient economically advantageous production of high-purity metallic Ti and can find wide applications.
