Sodium nitrate can be used in the production of nitric acid by combining it with sulfuric acid and subsequent separation through fractional distillation of the nitric acid, leaving behind a residue of sodium bisulfate. Hobbyist gold refiners use sodium nitrate to make a hybrid aqua regia that dissolves gold and other metals.
Sodium nitrate is also a food additive used as a preservative and color fixative in cured meats and poultry; It is listed under its INS number 251 or E number E251. It is approved for use in the EU, USA and Australia and New Zealand. Sodium nitrate should not be confused with sodium nitrite, which is also a common food additive and preservative used for example, in deli meats.
Less common applications include as an oxidizer in fireworks replacing potassium nitrate commonly found in black powder and as a component in instant cold packs.
Sodium nitrate is used together with potassium nitrate and calcium nitrate for heat storage and, more recently, for heat transferin solar power plants. A mixture of sodium nitrate, calcium nitrate and potassium nitrate is used as energy storage material in prototype plants, such as Andasol Solar Power Station and the Archimede project.
It is also used in the wastewater industry for facultative microorganism respiration. Nitrosomonas, a genus of microorganisms, consumes nitrate in preference to oxygen, enabling it to grow more rapidly in the wastewater to be treated.
Sodium Nitrate is also sometimes used by marine aquarists who utilize carbon dosing techniques. It is used to increase nitrate levels in the water and promote bacterial growth
