摘要： PROBLEM TO BE SOLVED: To economically and highly efficiently produce metallic Ti or Ti alloy having high purity without using an expensive reducing agent. SOLUTION: A molten salt containing CaCl 2 and having Ca dissolved therein is held in a reaction vessel 1. The gas of TiCl 4 as the raw material of Ti is fed into the molten salt in the reaction vessel 1. In the molten salt, TiCl 4 is reduced in a wide region in the reaction vessel 1 by dissolved Ca in the molten salt to efficiently generate particulate metallic Ti. The generated Ti particles are settled without being flocculated to deposit on the bottom part of the vessel, and are exhausted to the outside of the vessel one by one. The molten salt in which Ca has been consumed after used for the generation of Ti is fed to an electrolytic cell 7, and Ca is generated and replenished by the electrolysis of the molten salt. Thereafter, it is returned to the reaction vessel 1. By the circulation of the molten salt and the operation for the concentration of ca in the process thereof, the metallic Ti is economically produced without independently extracting and separately replenishing Ca.

摘要： PROBLEM TO BE SOLVED: To produce metal Ti with high efficiency by a Kroll process where TiCl
4 is reduced with Mg.
SOLUTION: A molten salt containing CaCl
2 and having Ca dissolved therein is held in a reaction vessel 1. The gas of TiCl
4 as the raw material for Ti is fed into the molten salt within the reaction vessel 1. In the molten salt within the reaction vessel 1, TiCl
4 is reduced in a wide region by the dissolved Ca in the molten salt, and granular metal Ti is efficiently produced. The similar molten salt is held in an electrolytic cell 2 and is electrolyzed at an anode 6 and a cathode 7, thus Ca is produced on the side of the cathode 7. As the cathode 7, a molten Ca alloy 9 is used, and Ca produced on the side of the cathode 7 is absorbed into the molten Ca alloy 9. The molten Ca alloy 9 in which the concentration of Ca is enhanced is transported to the reaction vessel 1 and is brought into contact with the molten salt in the reaction vessel 1, thus Ca is fed to the molten salt. Ca consumed in accordance with the production reaction of Ti is compensated, and the production reaction of Ti is continued. The molten Ca alloy 9 in which the concentration of Ca is lowered in the reaction vessel 1 is reversely fed to the electrolytic cell 2, and the concentration of Ca is recovered.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing metal Ti with high efficiency by a kroll process where TiCl 4 is reduced with Mg. SOLUTION: A mixed molten salt comprising CaCl 2 and NaCl is held at ≤600°C within a reaction tank 1. Na is introduced into the reaction tank 1, and further, TiCl 4 as a Ti raw material is introduced therein. The Na introduced into the reaction tank 1 is made into Ca, is dissolved into the molten salt and reduces the TiCl 4 introduced into the molten salt, thus Ti grains are produced. The produced Ti grains are introduced into a separation tank 2 together with the molten salt, and the Ti grains and Na are separated from the molten salt. The remaining molten salt is introduced into an electrolytic cell 3, and is electrolyzed at a high temperature of ≥600°C to produce Na. The produced Na is returned to the reaction tank 1, and replenishes the Na consumed in the reaction tank 1. Utilizing the reverse reaction by the temperature change in the molten salt with 600°C as a critical point, Ca having high reactivity is not directly used but easily treatable Na is circularly used, thus the production of Ti by Ca reduction is economically performed.

Still further, when a conductive porous material is used as the negative electrode, enhanced productivity can be realized.
