Abstract (en)
Provided is a method for producing metal titanium by molten salt electrolysis using a conductive material containing titanium, aluminum, oxygen and other impurities. A method for producing metal titanium, wherein a refining process includes: a rough electrodeposition step of performing a molten salt electrolysis using an electrode containing a TiAlO conductive material in a chloride bath Bf to obtain a titanium-containing electrodeposit TC ; and one or more refinement electrodeposition steps of performing a molten salt electrolysis using an electrode containing the titanium-containing electrodeposit TC in a chloride bath Bf, and wherein at least one of the chloride bath Bf used for the rough electrodeposition step and the chloride bath Bf used for the refinement electrodeposition step contains 30 mol % or more of magnesium chloride.
