CMI researchers from Ames National Laboratory conducted the activity for this highlight
Achievement
REMAFS (Rare Earth Metals via Alternative Fluoride Salts) won Gold in the 2025 R&D 100 Special Recognition: Green Technology for a non-toxic process that removes hydrofluoric acid from rare-earth metal production.
Details
- REMAFS provides a novel pathway for rare-earth metals production by using an alternative fluoride salt prepared without hydrofluoric acid (HF) and at room temperature.
- This HF-free approach improves safety, scalability and lowers environmental impact.
- It has been used for high performance permanent magnets production and licensed for rare earth metal production in USA.
Hub Targets Addressed
Win industry adoption of three CMI developed technologies.
