Title:
METHOD FOR PRODUCING ELECTRODEPOSIT
Document Type and Number:
WIPO Patent Application WO/2023/007918
Kind Code:
A1
Abstract:
This method for producing an electrodeposit is a method for producing a Ti-containing electrodeposit by means of electrolytic purification using molten salt electrolysis, the method comprising an electrodeposit step in which an electrode 3 having a negative electrode 3b and a positive electrode 3a containing a crude titanium-based material containing Ti, Al, and O and having conductivity is used in a chloride bath as a molten salt bath Bm, and a purified titanium-based material is deposited on the negative electrode 3b to obtain an electrodeposit, wherein in the electrodeposit step, the electrode 3 has a plurality of positive electrodes 3a, and the use completion time of some positive electrodes 3a among the plurality of positive electrodes 3a is shifted to the use completion time of the remaining positive electrodes 3a so that a purified titanium-based material is deposited on the negative electrode 3b.
