Ammonium nitrate
Ammonium nitrate is a chemical compound, the nitrate salt of the ammonium cation. It has the chemical formula NH₄NO₃, simplified to N₂H₄O₃. It is a white crystal solid and is highly soluble in water. It is predominantly used in agriculture as a high-nitrogen fertilizer. Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices. Many countries are phasing out its use in consumer applications due to concerns over its potential for misuse.
