Title:
PROCESS FOR PRODUCING Ti AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2007/034645
Kind Code:
A1
Abstract:
A process for producing Ti, comprising the reduction step of providing a molten salt
containing CaCl2 and having Ca dissolved therein and reacting TiCl4
with the Ca to thereby form Ti particles, the separation step of separating the
Ti particles formed in the molten salt from the molten salt and the electrolysis
step of electrolyzing the molten salt so as to increase the concentration of Ca,
wherein the molten salt having the concentration of Ca increased in the electrolysis
step is introduced in a regulation vessel to thereby render the Ca concentration
of the molten salt constant and thereafter is used in the reduction of TiCl4
in the reduction step. In this process, not only can any fluctuation of Ca concentration
of molten salt charged in a reduction vessel be suppressed but also a high concentration
thereof can be maintained. Further, continuous processing of a large volume
of molten salt becomes feasible. Therefore, the reduction reaction of TiCl4
can be efficiently performed, and as a process for realization of Ti production
on an industrial scale, the process can be effectively utilized in the production
of Ti by Ca reduction.
