Is ANFO a mixture?
Ammonium nitrate fuel oil (ANFO) is one of the most favorite explosives used in terrorist attacks. This explosive is a complex mixture of 95-96% ammonium nitrate (AN) and 4-5% liquid hydrocarbons (fuel oil).
Which fuel oil is used in ANFO?
The usual ANFO formulation contains about 94% by weight ammonium nitrate (AN) and 6% diesel fuel oil (FO).
What causes orange smoke in an explosion?
The orange/red coloration is caused by the presence of NO2 which is a direct product of the detonation process, and is also produced in the after burning reactions and by the secondary oxidation of NO to NO2 as the cloud mixes with air.
