Ammonium Fluoride

Ammonium fluoride is an inorganic chemical compound with the chemical formula NH₄F and CAS Number 12125-01-8. It is white crystalline hygroscopic element which is exceedingly soluble in water and is slightly soluble in alcohol and insoluble in liquid ammonia.

Preparation of Ammonium Fluoride

Ammonium fluoride is synthesized by adding ammonia gas to cold hydrofluoric acid at about 10-degree Celsius temperature.

NH₃ + HF → NH₄F

It can also be prepared with silicon tetrafluoride gas and ammonia of high purity as reactants. Equations:

3SiF₄ + 2H₂O → 2H₂SiF₆ + SiO₂

H₂SiF₆ + 2NH₃ → (NH₄)₂SiF₆

(NH₄)₂SiF₆ + 4NH₃ + 2H₂O → SiO₂ + 6NH₄F

Ammonium Fluoride Uses

• Ammonium fluoride is used in the etching of the glasses and related silicates, polishing metal surfaces, extracting rare metals and disinfection.

• Brewing industry buy ammonium fluoride to use it for preservation.

• It is used as a masking agent, preservative and reagents for the analysis.

• It is having application in wood preservation, spot analysis of zirconium and glass engraving.

Toxicity

If swallowed, inhaled or skin contact causes acute toxicity. Inhalation of ammonium fluoride can cause irritation on the respiratory tract and ingestion can be fatal. Skin contact can result in burning sensation and exposure of it through eyes can irritate the mucus membrane.
