摘要： A process for producing Ti, comprising a reduction step of reacting TiCl 4 with Ca in a CaCl 2 -containing molten salt having the Ca dissolved therein to thereby form Ti particles, a separation step of separating the Ti particles formed in said molten salt from said molten salt and an electrolysis step of electrolyzing the molten salt so as to increase the Ca concentration, wherein the molten salt increased in Ca concentration in the electrolysis step is introduced into a regulating cell to thereby render the Ca concentration of the molten salt constant and thereafter the molten salt is used for the reduction of TiCl 4 in the reduction step. In the present invention, the Ca concentration of the molten salt to be fed to the corresponding reduction vessel can be inhibited from fluctuating and, at the same time, can maintain high concentration levels. Further, a large volume of the molten salt can be treated continuously. Therefore, the reduction reaction of TiCl 4 can be efficiently performed, and the process can be effectively utilized in the production of Ti by Ca reduction as a production process for realizing Ti production on an industrial scale.

摘要： The present invention provides a method for electrolyzing molten salt that can enhance the concentration of metal-fog forming metal in the molten salt by carrying out the electrolysis under conditions that the molten salt containing the chloride of metal-fog forming metal is supplied from one end of an electrolytic cell to a space between an anode and a cathode in a continuous or intermittent manner to provide a flow rate in one direction to the molten salt in the vicinity of the surface of the cathode and thus to allow the molten salt to flow in one direction in the vicinity of the surface of the cathode. According to the present invention, while high current efficiency is maintained, only the molten salt enriched with metal-fog forming metal such as Ca can be effectively taken out. Further, this method can easily be carried out by using the electrolytic cell according to the present invention. Furthermore, the application of the method for electrolyzing molten salt according to the present invention to the production of Ti by Ca reduction can realize the production of metallic Ti with high efficiency. Thus, the method for electrolyzing molten salt, the electrolytic cell, and the process for producing Ti, each according to the present invention, can be effectively utilized in the production of Ti by Ca reduction.
