Applications

Sodium fluoride is used as a steel degreasing agent and in tin electroplating, flux, heat treating salt compositions, fluoridation of drinking water, removing HF from exhaust systems to reduce air pollution, and frosting glasses. It serves as a source of fluoride ion in several applications including it use in synthetic chemistry, for example in Finkelstein reaction for preparating fluoro compounds, desilylation in sensitive organic compounds, metallurgy, and reaction with electrophilic chlorides. It has medical and other applications including complexing of magnesium ions.

Notes

It must be kept away from oxidizing agents, metals, acids, alkalis. It is less hygroscopic.
