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 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.

Preferably, to be used is a diaphragm comprising a porous ceramic body having a purity of yttrium of 90 mass % or more (more preferably, 99% or more), a porosity of 1% or more and a pore diameter of 20 μm or less, and having a thickness of 0.05-50 mm and a metal halide is used as the electrolytic bath. The method can be utilized for producing metals such as calcium or rare earth elements, in particular. For example, when the method is applied to the production of calcium, metallic calcium can be produced with ease and at low cost without the need for enormous heat energy.

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： In producing Ti or a Ti alloy through reduction by Ca, an electrolytic-bath salt taken out from a reduction process is electrolyzed to recover Ca and the electrolytic-bath salt as a solid substance, and the recovered Ca and electrolytic-bath salt are delivered to the reduction process. Therefore, heat generation is suppressed in the reduction process by utilizing latent heat of fusion possessed by the solid substance, thereby largely improving production efficiency and thermal efficiency. Additionally, a reaction temperature is easily controlled, and a raw-material loading rate can be enhanced to efficiently produce Ti or the Ti alloy. At this point, using a pulling electrolysis method of the invention, the solid-state Ca and electrolytic-bath salt can be obtained at a low voltage and high current efficiency, i.e., with the relatively small power consumption. When the solid-state Ca and electrolytic-bath salt is used as a Ca source in producing Ti or the Ti alloy through reduction by Ca, the Ti or Ti alloy can efficiently be produced.
