Molecule Structure Image



Potassium nitrate occurs as a mineral niter and is a natural solid source of nitrogen. Major uses of potassium nitrate are in fertilizers, rocket propellants and fireworks. It is also used as a food additive. It is also commonly used in the heat treatment of metals as a solvent in the post-wash. The oxidizing, water solubility and low cost make it an ideal short-term rust inhibitor. It is also used as chemical raw material for glass and ceramic industry.
