Title:
METHOD FOR PREPARING TITANIUM METAL BY MEANS OF MOLTEN SALT ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2022/237512
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing titanium metal by means of molten salt electrolysis. The method comprises constructing an electrochemical system, wherein an anode chamber is filled with an anode molten salt electrolyte containing a titanium raw material and has an anode, and a cathode chamber is filled with a cathode molten salt electrolyte and has a cathode, and the anode molten salt electrolyte and the cathode molten salt electrolyte do not come into contact with each other, but are in communication with each other by means of a liquid alloy at the bottom of an electrolytic cell; and powering on the system for electrolysis so as to obtain a titanium metal product at the cathode. The method of the present invention has the advantages of low requirements for the titanium raw material, continuous operation, and relatively higher quality titanium metal being able to be directly obtained.
