FAQ

Frequently Asked Questions

Yes. It is corrosive, toxic, and reacts violently with water, releasing toxic hydrogen fluoride gas. It requires careful handling in a controlled laboratory environment.

The chemical formula is SbF₃.

Antimony trifluoride (SbF₃) contains one antimony atom bonded to three fluorine atoms. Antimony pentafluoride (SbF₅) contains one antimony atom bonded to five fluorine atoms. They have different chemical properties and uses; SbF₅ is a much stronger Lewis acid.

Its use is almost exclusively confined to chemical research, specialized industrial synthesis, and as a component in some very specific manufacturing processes (e.g., for certain dyes or fluoride glasses). It is not a household or general-use chemical.
