In the crystalline state, it is a colorless, nonvolatile, slightly hygroscopic, odorless substance. Potassium nitrate is highly soluble in water. Practically non-toxic to living organisms.

It is mainly used in pyrotechnics as a potassium-nitrogen fertilizer (a very convenient combination of two elements that are usually poorly combined when assimilated by plants).
