CMI Project 2.2.5 Bypassing electrolysis: one-step calciothermic route to NdFeB powders from Nd2O3

The primary objective of the proposed research is to develop a domestic one-step environmentally-friendly production methodology, which can directly convert neodymium oxide (Nd2O3) into neodymium iron boron (NdFeB) hard-magnetic powders. The proposed innovative method employs a calciothermic reduction process circumventing expensive and environmentally detrimental production of Nd metal, typically performed in industry through electrolysis, while mitigating greenhouse gas emissions by effectively eliminating the necessity for additional energy-intensive steps like strip casting. The implementation of the proposed calciothermic reduction technology in the United States will reduce reliance of U.S. economy on foreign suppliers of materials for permanent magnets.
