Potassium Nitrate

Potassium Nitrate

Potassium Nitrateis a crystalline salt, KNO3; a strong oxidizer used especially in making gunpowder, as a fertilizer, and in medicine.

Potassium nitratehas a chemical formula of KNO3. It is an ionic salt ofpotassiumions K+ andnitrateions NO3−, and is therefore an alkali metalnitrate. It is a natural source ofnitrateand has been used as a constituent for several different purposes, including food preservatives, fertilizers, tree stump removal, rocket propellants and fireworks.Potassium nitrateis a common active ingredient in dentrifices where it exerts an antisensitivity action. It provides increasing protection against painful sensitivity of the teeth to cold, heat, acids, sweets or contact.

 

POTASSIUM NITRATEis a white to dirty gray crystalline solid.Watersoluble. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers.
