Sodium Nitrate for Glass Manufacturing
Sodium nitrate is the chemical compound with the formula NaNO3.
This salt is also known as Chile saltpeter or Peru saltpeter to distinguish it from ordinary saltpeter, potassium nitrate.

- It is used in Glass Manufacturing.
- It can be combined with iron hydroxide to make a synthetic resin .
- 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.
- 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 transfer in 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 waste water 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.
- Dental use : Mouthwash and gels containing Sodium Nitrate are used in treatment of dentine hypersensitivity.
