METHOD FOR PRODUCING TITANIUM FOIL OR TITANIUM PLATE, AND CATHODE ELECTRODE

Title:

METHOD FOR PRODUCING TITANIUM FOIL OR TITANIUM PLATE, AND CATHODE ELECTRODE

Document Type and Number:

WIPO Patent Application WO/2018/159774

Kind Code:

A1

Abstract:

In the present invention, using a molten salt electrolytic deposition method in which a constant-current pulse is used, a titanium electrodeposition film is formed on a surface of a cathode electrode constituted of glassy carbon, graphite, Mo, and Ni, and then by applying an external force to the titanium electrodeposition film and/or removing the cathode electrode, the titanium electrolytic deposition film is separated from the cathode electrode to produce a titanium foil or a titanium plate. Due to this configuration, it is possible to peel off the titanium electrolytic deposition film, which has been electrolytically deposited on the cathode electrode, from the cathode electrode in a simple manner and at a low cost.
