FAQ.
Q: Advantages over cryolite?
A: Lower melting point (580°C vs 1012°C), 30% less fluorine loss, better for modern aluminum electrolysis.
Q: How to select proper grade?
A: Industrial for smelting, electronic for packaging, high purity for research.
Q: Latest developments?
A: Nano-grade KAlF₄ (<100nm) in development for enhanced electronic applications.
