Research Progress on Preparation of La Alloy by Molten Salt Electrolysis

Lanthanum ranks first among rare earth elements and accounts for a large proportion of the total rare earth elements. It is rich in resources. La alloys have many applications in hydrogen storage materials, magnetic refrigeration, metal targets, and steel modification. This paper systematically introduces the latest research progress of La-Zn, La-Cu, La-Ni, and La-Al alloys prepared by molten salt electrolysis, compares and summarizes its application fields and the electrochemical behavior of La ions in molten salt. To make suggestions for future basic research and applied research directions.
