White Powder Sodium Nitrate Salt For Industrial / High Purity Natrium Nitrate

White Powder Sodium Nitrate for industrial / High purity Soda Niter

Sodium nitrate is the oldest known nitrogenous fertilizer. It is a white, shiny crystal available in nature as Chilean saltpeter or Chilean nitrate. Sodium nitrate is manufactured by two methods. In the first, known as the Guggenheim method, the fertilizer is extracted from a mined product, called caliche, mined mostly in Chile; hence the name (Chilean saltpeter or Chilean nitrate). The caliche is dissolved in warm water and then cooled to 0°C to produce sodium nitrate crystals, which are circulated through heat exchangers. The circulation keeps the crystals suspended, to finally form pellets. Caliche mined in Chile, contains sodium nitrate (8 to 20%), potassium and magnesium nitrates and salts like borates, sulphates and chlorides. Approximately, one ton of sodium nitrate of 99% purity is obtained from 10 tons of caliche. Sodium nitrate is shipped in airtight containers. The pellets are also coated to impart free-flowing characteristics. Sodium nitrate is also manufactured from nitric acid and soda ash, using salt and oyster shells. Nitric acid is reacted with soda ash forming sodium nitrate solution. Most water is removed by evaporation and the rest is heated to a high temperature and sprayed through nozzles. Sodium nitrate solidifies as pellets while coming through the nozzles. Sodium nitrate fertilizer is water-soluble. It contains 16% nitrogen and about 26% sodium. Plants absorb most of the nitrogen in a nitrate form and sodium nitrate is a commonly preferred fertilizer, although the nitrogen content of sodium nitrate is lesser than that in many other inorganic nitrogen fertilizers. Sodium nitrate has a neutralizing effect on soil acidity because of its inherent basic residual effect. Its neutralizing value is 0.82 kg of calcium carbonate equivalent to 0.45 kg of sodium nitrate. The field crops which benefit most from sodium nitrate application are sugar beet and cotton. If applied excessively, sodium nitrate can damage the soil structure by reducing the flocculation. But normal applications of 100 to 200 kg of fertilizer/hectare/year do not affect the soil structure.
