Title:
DEVICE AND METHOD FOR DIRECTLY REDUCING METAL COMPOUND TO PREPARE METAL OR ALLOY POWDER
Document Type and Number:
WIPO Patent Application WO/2020/168582
Kind Code:
A1
Abstract:
A device and method for directly reducing a metal compound to prepare metal or alloy powder. The method comprises: under a protective atmosphere containing water vapor, taking a metal plate (11) as a cathode, taking graphite (9) as an anode, and taking metal chloride as molten salt (13); placing a metal compound (12) to be treated in the molten salt (13); at a temperature between a melting temperature of the molten salt +10°C and a boiling temperature of the molten salt -100°C, performing electrochemical electrolysis reaction at the voltage of 0.5-4.1 V to obtain molten salt containing metal or alloy powder; and cooling to a room temperature along with a furnace, and separating the solidified salt from the metal or alloy powder.
