CMI researchers from Ames National Laboratory conducted the activity for this highlight
Innovation
A CMI technology developed at Ames National Laboratory is now licensed to Principal Mineral, bringing the cumulative total of CMI technologies licensed to 25.
Achievement
- The Rare Earth Metals via Alternative Fluoride Salt (REMAFS) process is based on metallothermic reduction of Na-RE-F or similar salts, produced without the use or generation of HF.
- The CMI project team has demonstrated that the REMAFS achieves an equivalent magnet grade (N40) compared with a magnet of similar elemental constitution made with commercially available rare earth metals.
Significance and Impact
This technology supports domestic neodymium metal and Nd-Fe-B magnet production.
Hub Targets Addressed
- Win industry adoption of three CMI developed technologies
- Energy-efficient REE metal production
