METHOD AND DEVICE FOR PRODUCTION OF Ti BY MEANS OF Ca REDUCTION

摘要

A process for producing Ті through Ca reduction, comprising providing an apparatus including a reaction vessel for retaining a molten salt containing CaCland having Ca dissolved therein, an electrolytic vessel for retaining a molten salt containing CaCland 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 TiClinto the reaction vessel to thereby form Ті. This process is economically advantageous as the feeding rate of TiClas a raw material can be increased, as continuous production can be effected, and as Ca consumed by reduction reaction of TiClcan be replenished by electrolysis of CaCl. Thus, this process can be effectively utilized as means for efficient economically advantageous production of high-purity metallic Ті and can find wide use.
