ANFO - Wikipedia

Chemistry. The chemistry of ANFO detonation is the reaction of ammonium nitrate with a long-chain alkane (C n H 2n+2) to form nitrogen, carbon dioxide, and water.In an ideal stoichiometrically balanced reaction, ANFO is composed of about 94.3% AN and 5.7% FO by weight. In practice, a slight excess of fuel oil is added, as underdosing results in reduced performance while overdosing merely ...

ammonium nitrate | Formula, Uses, & Facts | Britannica

Ammonium nitrate is a colourless crystalline substance (melting point 169.6 °C [337.3 °F]). It is highly soluble in water; heating of the water solution decomposes the salt to nitrous oxide (laughing gas). Because solid ammonium nitrate can undergo explosive decomposition when heated in a confined space, government regulations have been imposed on its shipment and storage.
