	==Applications==		== Synthesis ==
			Sodium nitrate is also synthesized industrially by neutralizing ] with ] or ]:
	Sodium nitrate was used extensively as a ] and a raw material for the ] of ] in the late 19th century. It can be combined with ] to make a ].
			:2 HNO<sub>3</sub> + Na<sub>2</sub>CO<sub>3</sub> → 2 NaNO<sub>3</sub> + H<sub>2</sub>O + CO<sub>2</sub>
	Sodium nitrate should not be confused with the related compound, ]. Sodium nitrate in the brine gives cooked corned beef its classic reddish color (without it corned beef comes out gray), and it kills botulism spores. Nitrate is actually changed to nitrite by bacterial action during processing and storage and nitrate itself has no effect on meat color.
			:HNO<sub>3</sub> + NaHCO<sub>3</sub> → NaNO<sub>3</sub> + H<sub>2</sub>O + CO<sub>2</sub>
	It can be used in the production of ] by combining it with ] and subsequent separation through ] of the nitric acid, leaving behind a residue of ]. ] gold refiners use sodium nitrate to make a hybrid ] that dissolves gold and other metals.
			or also by neutralizing it with ] (however, this reaction is very exothermic):
	Less common applications include its use as a substitute oxidizer used in fireworks as a replacement for ] commonly found in ] and as a component in instant cold packs.<ref>Albert A. Robbins "Chemical freezing package" {{US patent|2898744}}, Issue date: August 1959</ref>

	Sodium nitrate is used together with ] for heat storage and, more recently, for ] in ] plants.
			or by mixing stoichiometric amounts of ] and ], ] or ]:
	It is also used in the wastewater industry for facultative microorganism respiration. ], a genus of ]s, consumes nitrate in preference to oxygen, enabling it to grow more rapidly in the wastewater to be treated.
			:NH<sub>4</sub>NO<sub>3</sub> + NaOH → NaNO<sub>3</sub> + NH<sub>4</sub>OH
			:NH<sub>4</sub>NO<sub>3</sub> + NaHCO<sub>3</sub> → NaNO<sub>3</sub> + NH<sub>4</sub>HCO<sub>3</sub>
			:2NH<sub>4</sub>NO<sub>3</sub> + Na<sub>2</sub>CO<sub>3</sub> → 2NaNO<sub>3</sub> + (NH<sub>4</sub>)<sub>2</sub>CO<sub>3</sub>
			==Uses==
			Most sodium nitrate is used in fertilizers, where it supplies a water-soluble form of nitrogen. Its use, which is mainly outside of high-income countries, is attractive since it does not alter the ] of the soil. Another major use is as a complement to ] in explosives. Molten sodium nitrate and its solutions with potassium nitrate have good thermal stability (up to 600&nbsp;°C) and high heat capacities. These properties are suitable for thermally annealing metals and for storing thermal energy in solar applications.<ref name=Ullmann>{{Ullmann|doi=10.1002/14356007.a17_265|title=Nitrates and Nitrites|year=2000|last1=Laue|first1=Wolfgang|last2=Thiemann|first2=Michael|last3=Scheibler|first3=Erich|last4=Wiegand|first4=Karl}}</ref>

	Sodium nitrate and nitrite are associated with a higher risk of ].<ref></ref> ],<ref>, World Cancer Research Fund (2010) accessdate 2010-03-06</ref> states that one of the reasons that processed meat increases the risk of ] is its content of nitrate. A small amount of the nitrate added to meat as a preservative breaks down into nitrite, in addition to any nitrite that may also be added. The nitrite then reacts with protein-rich foods (such as meat) to produce N-nitroso compounds (NOCs). Some types of NOCs are known to cause cancer. NOCs can be formed either when meat is cured or in the body as meat is digested.		Substantial evidence in recent decades, facilitated by an increased understanding of pathological processes and science, exists in support of the theory that processed meat increases the risk of ] and that this is due to the nitrate content. A small amount of the nitrate added to meat as a preservative breaks down into nitrite, in addition to any nitrite that may also be added. The nitrite then reacts with protein-rich foods (such as meat) to produce ]ic NOCs (] compounds). NOCs can be formed either when meat is cured or in the body as meat is digested.<ref>, {{Webarchive |url=https://web.archive.org/web/20190726222247/https://www.wcrf.org/sites/default/files/SLR_colorectal_cancer_2010.pdf |date=2019-07-26 }} World Cancer Research Fund (2010)</ref>
			However, several things complicate the otherwise straightforward understanding that "nitrates in food raise the risk of cancer". Processed meats have no fiber, vitamins, or phytochemical antioxidants, are high in sodium, may contain high fat, and are often fried or cooked at a temperature sufficient to degrade protein into nitrosamines. Nitrates are key intermediates and effectors in the primary vasculature signaling which is necessary for all mammals to survive.<ref>{{cite journal |last1=Machha |first1=Ajay |last2=Schechter |first2=Alan N. |date=August 2011 |title=Dietary nitrite and nitrate: a review of potential mechanisms of cardiovascular benefits |journal=European Journal of Nutrition |volume=50 |issue=5 |pages=293–303 |doi=10.1007/s00394-011-0192-5 |issn=1436-6207 |pmc=3489477 |pmid=21626413}}</ref>
