| Sodium nitrate (not to be confused with sodium nitride) is a type of salt (NaNO3) which has long been used as an ingredient in explosives and in solid rocket propellants, as well as in glass and pottery enamel, and as a food preservative (such as in hot dogs), and has been mined extensively for those purposes. It is also variously known as caliche, Chile saltpeter, saltpeter, and soda niter. This article does not cite its references or sources. ...
Caliche is a hardened deposit of calcium carbonate. ...
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. Atacama The Atacama Desert of Chile is a virtually rainless plateau made up of salt basins (salares), sand, and lava flows, extending from the Andes mountains to the Pacific Ocean. ...
Humberstone and Santa Laura Saltpeter Works are two former saltpeter refineries located in northern Chile. ...
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 caliche. R-phrases S-phrases Supplementary data page Structure and properties n, εr, etc. ...

Sodium nitrate is also manufactured synthetically by reacting nitric acid with soda ash. Sodium carbonate (also known as washing soda or soda ash), Na2CO3, is a sodium salt of carbonic acid. ...
Applications
The compound has antimicrobial properties when used as a food preservative. It is found naturally in leafy green vegetables. It has possible health benefits for increasing oxygen to blood,[citation needed] as well as known health side effects in particular at high doses. Side effects may include increased risk of cancer (if intake occurs together with proteins, which builds carcinogenic nitrosamines), where according to MEDEM the US-NAS found no such evidence in experiments with laboratory animals. In case of overdosage the local poison control center is the contact of choice. A preservative is a natural or synthetic chemical that is added to products such as foods, pharmaceuticals, paints, biological samples, etc. ...

It can be used in the production of nitric acid by combining with sulfuric acid and subsequent separation through fractional distillation of the nitric acid, leaving behind a residue of sodium bisulfate. The chemical compound nitric acid (HNO3), also known as aqua fortis and spirit of nitre, is an aqueous solution of hydrogen nitrate (anhydrous nitric acid). ...
Sulfuric acid (British English: sulphuric acid), H2SO4, is a strong mineral acid. ...
Fractional distillation is the separation of a mixture into its component parts, or fractions, such as in separating chemical compounds by their boiling point by heating them to a temperature at which several fractions of the compound will evaporate. ...
Sodium bisulfate, also sodium hydrogen sulfate, has formula NaHSO4. ...
Less common applications include an oxidizer used in gunpowder, in blackpowder rockets, and as replacement for potassium nitrate. Smokeless powder Gunpowder, whether black powder or smokeless powder, is a substance that burns very rapidly, releasing gases that act as a propellant in firearms. ...
Black powder is a type of gunpowder invented in the 9th Century and practically the only propellant and explosive known until the middle of the 19th Century. ...
