摘要： 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.

摘要： Provided is a method for producing a titanium-containing electrodeposit, which can achieve good refinement by an electrodeposition without using the Kroll method. A method for producing a titanium-containing electrodeposit, including an electrodeposition step of electrodepositing a titanium-containing electrodeposit in a chloride bath, the chloride bath being a molten salt, using an anode including a TiAlO conductive material containing titanium, aluminum, and oxygen, and a cathode, wherein, in the electrodeposition step, a current density of the cathode is in a range of 0.3 A/cm2 or more and 2.0 A/cm2 or less, and wherein the chloride bath contains 1 mol% or more of a titanium subchloride.
