용도

Potassium nitrate has a vast variety of applications. Appropriate preparations of potassium nitrate find use in fertilizers, food preservatives, tooth paste, rocket propellants and fireworks. In addition, it is also used as an electrolyte in a salt bridge, and as thermal storage medium in power generation systems. It forms phase change material with silica and alumina nanoparticles. In combination with boron trifluoride it forms an efficient reagent for nitration of aromatic compounds. Adsorption on alumina provides an environmentally benign aromatic nitrating agent.

참고

It is an oxidizer. Stable under ordinary conditions. Incompatible with reducing agents and alcohols.
