Abstract

A method for producing Ti or a Ti alloy using the reduction by Ca, which comprises a reduction step of holding a molten salt containing CaCl2 and having Ca dissolved therein in a reaction vessel (1) and reacting Ca in the molten salt with a metal chloride containing TiCl4, to generate Ti particles or Ti alloy particles in the molten salt, and a separation step (7) of separating Ti particles or Ti alloy particles being formed in the molten salt from the molten salt. It is preferred to further add an electrolysis step (8) of electrolyzing the CaCl2 withdrawn out of the reaction vessel (1) into Ca and Cl2 and using the formed Ca for the reaction in the reaction vessel (1) for forming Ti or a Ti alloy. In the electrolysis step (8), the use of an alloy electrode comprising a molten Ca alloy as a cathode is effective for the improvement of electric current efficiency and the molten Ca alloy can also be utilized effectively as a medium for transporting Ca in order to enhance a Ca concentration. The above method allows the production of a metallic Ti having high purity with good efficiency at a low cost.
