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.

摘要： A process for producing Ti, comprising a reduction step of reacting TiCl4 with Ca in a CaCl2-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 TiCl4 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 TiCl4 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.

A molten salt containing CaCl2 and having Ca dissolved therein is held in a reactor cell, electrolysis is performed in the molten salt in the reactor cell, and particulate Ti or Ti alloys are generated in the molten salt by supplying a metallic chloride containing TiCl4 to the molten salt so as to react with Ca generated on a cathode electrode side by the electrolysis, allowing enhancement of a feed rate of TiCl4 as a raw material of Ti, and also a continuous operation. Further, the method by the invention eliminates the need of the separate handling of Ca, because a reducing reaction and an electrolytic reaction can simultaneously proceed in the reactor cell to replenish Ca, consumed in the reducing reaction, by the electrolytic reaction. Accordingly, the production method by the invention can be used as means for efficiently and economically producing high-purity Ti metals or Ti alloys.

摘要： The method by the invention in which a molten salt is held in a reactor cell 1 to perform electrolysis in the molten salt of the reactor cell, the molten salt containing CaCl2 while Ca being dissolved in the molten salt, and Ti or Ti alloys are generated in the molten salt by supplying a metallic chloride containing TiCl4 into the molten salt such that the metallic chloride containing TiCl4 is caused to react with Ca generated on a cathode electrode side by the electrolysis, makes it possible to produce the high-purity Ti metals or Ti alloy. Furthermore, the reactor cell 1 includes a membrane 4 which partitions an inside of the reactor cell into a side of an anode electrode 2 and a side of a cathode electrode 3, and the membrane 4 blocks the movement of Ca generated on the cathode electrode side in the reactor cell toward the anode electrode side while permitting the molten salt to flow in the reactor cell, which allows a back reaction by Ca to be effectively suppressed. When an electroconductive porous material is used as a cathode electrode, productivity can further be improved.

摘要： A mixed molten salt containing CaCl2 and NaCl is held in the reactor cell 1 at a temperature not more than 600° C. TiCl4 which is of a Ti raw material is introduced into the reactor cell 1 while Na is introduced into the reactor cell 1. Na introduced into the reactor cell 1 is replaced by Ca, Ca is dissolved in the molten salt, Ca reduces TiCl4 introduced into the reactor cell 1, and thereby Ti particles are generated. The generated Ti particles are introduced to a separation cell 2 along with the molten salt, and the Ti particles and Na are separated from the molten salt. The residual molten salt is introduced to an electrolytic cell 3 to generate Na by high-temperature electrolysis at the temperature more than 600° C. The generated Na is returned to the reactor cell 1 to replenish Na consumed in the reactor cell 1. The highly reactive Ca is not directly handled, and Na which is easy to handle is used in a circulating manner. Therefore, the Ti or Ti alloy can economically be produced by Ca reduction.
