Abstract: A method for producing Ti or a Ti alloy through the reduction of TiCl4 by Ca, which comprises holding a molten salt containing CaCl2 and having Ca dissolved therein in a reaction vessel and reacting Ca in the molten salt with a metal chloride containing TiCl4, to generate Ti particles or Ti alloy particles in the molten CaCl2. The above method allows the enhancement of the feed rate of TiCl4, which is the raw material of Ti, and also allows the continuous operation of the production, and thereby the production of a metallic Ti or a Ti alloy having high purity with good efficiency at a low cost can be attained. Further, the method eliminates the need for the replenishment of expensive metallic Ca and for the operation for separately handling Ca which is highly reactive and difficult to handle.
