Sodium nitrate (not to be confused with sodium nitrate or sodium nitrite) is the chemical compound with the formula NaNO3. This salt has long been used as an ingredient in fertilizers, explosives, and in solid rocket propellants, as well as in glass and pottery enamels; the compound has been mined extensively for those purposes.

Sodium nitrate was used extensively as a fertilizer and a raw material for the manufacture of gunpowder in the late nineteenth century. Sodium nitrate has antimicrobial properties when used as a food preservative. It is found naturally in leafy green vegetables. It can also be combined with iron hydroxide to make a resin.

The world's largest natural deposits of caliche ore were in the Atacama desert of Chile, and many deposits were mined for over a century, until the 1940s. The former Chilean saltpeter mining communities of Humberstone and Santa Laura were declared Unesco World Heritage sites in 2005.

Chile still has the largest reserves of caliche, with active mines in such locations as Pedro de Valdivia, Maria Elena and Pampa Blanca. Sodium nitrate, potassium nitrate, sodium sulfate and iodine are all obtained by the processing of c
aliche. Sodium nitrate is also synthesized industrially by neutralizing nitric acid with soda ash.
