Patent ID: 7648560

Claim:
A method for producing Ti or a Ti alloy through reduction by Ca, the method comprising: holding a molten salt in a reactor vessel, said molten salt containing CaCl 2 , Ca being dissolved in said molten salt, and reacting a metallic chloride containing TiCl 4 with Ca in the molten salt by introducing the metallic chloride into the molten salt to generate Ti particles or Ti alloy particles in said molten salt; separating the Ti particles or Ti alloy particles, generated in said molten salt, from said molten salt to leave a remaining molten salt containing CaCl 2 that is discharged outside the reactor vessel; electrolyzing the remaining molten salt containing CaCl 2 to generate an electrolyzing step output of a molten salt with a concentration of Ca increased with respect to the remaining molten salt; and returning the increased Ca concentration molten salt generated by said electrolysis step to the reactor vessel for the reacting step so as to be used for the generation reaction of Ti or the Ti alloy in the reactor vessel.
