25 Kilo Bag Option for Sodium Nitrate

Overview: What is Sodium Nitrate?

Also known as "Chile Saltpeter", Sodium Nitrate is a white granule or powder. With a range of industrial and food applications, you can find Nitrates as a preservative, colour fixative and additive for fertilisers. Its salty taste and odour, however, come from its sodium-based chemistry.

The sourcing and manufacture occur both in nature and synthetically. A large portion of Sodium Nitrate stocks come as a side effect of mining Caliche Ore, where you find Sodium Nitrate amongst the ore. The locations of these ores are traditionally within Chile and Peru, hence the name.

The other, and the synthetic route, is via chemical synthesis, by neutralising either Nitric Acid or Ammonium Nitrate with one of three products: Sodium Carbonate, Sodium Bicarbonate and Sodium Hydroxide. These create a range of reactions; two of which are below (Using Sodium Bicarbonate):

( 1 ) HNO3 + NaHCO3 = NaNO3 + H2O + CO2

( 2 ) NH4NO3 + NaHCO3 = NaNO3 + NH4 + HCO3

With applications, Sodium Nitrate is a common addition to a range of fertiliser products. As a water-soluble product, it is easily added to a range of liquid feeds, providing vital nutrition through its high nitrogen content, aiding in plant growth.

Additionally, you can find Sodium Nitrate in foods as a preservative and colour fixative in cured meats and poultry. However, it should not be confused with a similar product, Sodium Nitrite, with similar properties.

Finally, industrial applications range from thermal storage, pyrotechnics and smoke bombs to glass, enamel and even rocket propellant manufacture.
