Ammonium fluoride is a colorless crystal, easily soluble in water, spreading in moist air. Ammonium fluoride (fluoride) at -27,4 ° C forms a monohydrate, below 0 ° C - solid solutions with ice; when heated by aqueous solutions decomposes with the release of ammonia.
When burning or heating, toxic fumes are released.
Attacks metal and glass.
In case of contact with skin and mucous membranes, a chemical burn occurs.
With prolonged exposure, it has a destructive effect on the bones and teeth.
We also offer Ammonium Bifluoride.
