Title:
MOLTEN SALT ELECTROLYSIS TANK, METHOD FOR MANUFACTURING METAL MAGNESIUM USING SAME, AND METHOD FOR MANUFACTURING SPONGE TITANIUM
Document Type and Number:
WIPO Patent Application WO/2019/130378
Kind Code:
A1
Abstract:
A molten salt electrolysis tank comprising a bipolar electrode in which the tank efficiency is increased by preventing transient currents that flow from an anode to a cathode via through holes in a graphite bipolar electrode without contributing to electrolysis in a bipolar electrode section. Molten magnesium chloride is electrolyzed to manufacture metal magnesium using a molten salt electrolysis tank that comprises an electrolysis chamber and a metal recovery chamber and that has at least one bipolar electrode made of graphite with a pore volume per electrolysis cell unit in the electrolysis chamber of 0.12 mL/g or less. Further, sponge titanium is manufactured using this metal magnesium.
