REalloys Achieves 0.34% Oxygen Rare Earth Fluoride Without Hydrofluoric Acid
REalloys successfully demonstrated a patent-pending hydrofluoric acid-free fluorination process producing metallization-grade rare earth fluorides with just 0.34 wt% oxygen. This innovation could lower operating costs, reduce environmental and safety risks, and support scalable North American heavy rare earth supply chains for defense applications.
1. HF-free Fluorination Process Validation
REalloys conducted independent laboratory testing of its patent-pending hydrofluoric acid-free fluorination process, confirming production of rare earth fluorides with just 0.34 wt% oxygen—well below the 1 wt% threshold required for metallization-grade feedstock.
2. Safety and Cost Advantages
Eliminating hydrofluoric acid removes one of the most hazardous and corrosive reagents in rare earth processing, simplifying containment and handling, reducing environmental compliance burdens, and promising significant operating cost savings.
3. North American Supply Chain Impact
The HF-free platform strengthens domestic heavy rare earth metallization capabilities for high-performance magnets, diversifies supply away from conventional processes dominated by China, and is backed by newly filed patent applications covering the novel chemistry and process design.
