Description

Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
