Title:
METAL TITANIUM PRODUCTION METHOD AND METAL TITANIUM ELECTRODEPOSIT
Document Type and Number:
WIPO Patent Application WO/2022/230403
Kind Code:
A1
Abstract:
Provided is a metal titanium production method for producing metal titanium through molten salt electrolysis by using a conductive material containing titanium, aluminum, and oxygen. In this metal titanium production method, a refinement process comprises: a crude electrodeposition step for obtaining a titanium-containing electrodeposit TC by performing, in a chloride bath Bf, molten salt electrolysis using an electrode that contains a TiAlO conductive material; and at least one round of a refined electrodeposition step for performing, in a chloride bath Bf, molten salt electrolysis using an electrode that contains a titanium-containing electrodeposit TC. Regarding the chloride bath Bf used in the crude electrodeposition step and the chloride bath Bf used in the refined electrodeposition step, at least one of the chloride baths Bf contains 30 mol% or more of magnesium chloride.
