 Sodium nitrite is a white to slightly yellowish crystalline powder. It is very soluble in water and is also hygroscopic.

 Initiator in industrial explosives

Sodium nitrite is classified as an oxidising agent – similar to ammonium nitrate although they are very incompatible. The most commonly used gassing system is sodium nitrite coupled with sodium thiocyanate or urea in acetic acid medium.


Density reducing agent- Sodium nitrite chemically reacts with the base emulsion to produce density reducing gas bubbles. Sodium nitrite solution is widely used in emulsions to sensitise them by reacting with other chemicals in the matrix to form gas bubbles


Sodium Nitrite forms part of the chemical gassing compounds for better productivity (less mixing time) in the batch process and continuous production plants of emulsion.



It is added in small, measured and controlled quantities and the small quantity of heat released during the reaction is quickly dissipated in the mass of emulsion.To 100 parts of a non-explosive matrix 0.25% gassing agent (10% sodium nitrite) is added and thereafter 10% AN prills is mixed into the matrix before delivering the product into the blast hole.

However, if it is added in excess there may be localised heating that could cause decomposition of the emulsion.


Sodium nitrite reacts with ammonium nitrate to form an explosive compound – ammonium nitrite.

Sodium nitrite must be stored in its own unique store. It must be clearly labelled to avoid being confused with sodium nitrate where the latter is also used in the same process.

Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with clothing and other combustible materials. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
