Method for producing ti or ti alloy through reduction by ca (as amended)

A method for producing Ti or Ti alloys through reduction by Ca, comprising:

• a reduction electrolysis step in which a molten salt is held in a reactor cell to perform electrolysis using an electroconductive porous material as an cathode electrode 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 said molten salt by supplying a metallic chloride containing TiCl4 into said molten salt through said cathode electrode in order to cause the metallic chloride containing TiCl4 to react with Ca generated on a cathode electrode side by the electrolysis;
• and
• a Ti separation step of separating said Ti or Ti alloys from the molten salt inside the reactor cell or outside the reactor cell.
