Anwendungen

Potassium nitrate has several applications. It is used as an oxidizer, food preservative, fertilizer, and an active ingredient of condensed aerosol fire suppression systems. It is a powerful nitrating agent in sulfuric acid medium. In addition, it also used as an electrolyte in a salt bridge and thermal storage medium in power generation systems. Ternary salts containing potassium nitrate have been reported to improve the heat storage capacity in the molten salts.
