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.

A CaCl2-based molten salt containing Ca is held in a reduction chamber 1, a metal oxide is introduced into the molten salt in the reduction chamber 1, and the metal oxide is reduced with the Ca in the molten salt to form said metal. The metal formed in the molten salt is separated from the molten salt in a separation means 2, and the molten salt deprived of the metal is introduced into a chlorination chamber 7 and subjected to chlorination treatment with chlorine gas to eliminate the byproduct CaO in the molten salt. The molten salt after chlorination treatment is introduced into an electrolysis chamber 8 and electrolyzed for the formation of Ca and chlorine from CaCl2, and the thus-formed Ca or Ca-containing molten salt is transferred from the electrolysis chamber 8 to the reduction chamber 1. The chlorine obtained in the electrolysis chamber 8 is used in the chlorination chamber 7. Thus, the present invention provides a metal production method and an apparatus wherein high levels of productivity are obtained and the product metal can be inhibited from carbon contamination due to CaO, without any generation of CO2 from the production process, while their being based on the direct oxide reduction process comprising the step of reducing a metal oxide with Ca.

摘要： The invention is a method for producing Ti or Ti alloys through reduction of TiCl4 by Ca, which can produce high-purity Ti metals or Ti alloys. 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 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.
