Abstract
A method for preparing rare earth alloys by molten salt electrolysis using rare earth oxides as the raw material is provided, where the electrolytic cell used is divided into the anode chamber and the cathode chamber containing melts such as anolyte, catholyte and liquid alloy. The method has the advantages of continuous production, high operability, low requirements on raw material purity and high quality of rare earth alloy products.
Claims15
A method for preparing rare earth alloys, wherein the method is implemented by using an electrolytic cell divided into an anode chamber and a cathode chamber, wherein an anolyte and an anode are provided in the anode chamber, a catholyte and a cathode are provided in the cathode chamber, a liquid alloy is contained at a bottom of the electrolytic cell, and the anolyte and the catholyte are not in contact with each other but are connected via the liquid alloy;
- the cathode is a solid consumable cathode or a liquid cathode;
- and
- the method comprises:
- powering on the electrolytic cell to operate, adding a rare earth oxide raw material to the anode chamber, and obtaining a liquid rare earth alloy product in the cathode chamber.
