ammoniumnitratebased

Ammonium nitrate-based denotes compounds or formulations that rely on ammonium nitrate as the principal oxidizer. The term covers two broad categories: agricultural fertilizers used to supply nitrogen to crops, and industrial explosive formulations used in mining, construction, and demolition. The material is produced commercially and distributed in solid forms such as prills, pellets, or crystals, with differing grades for fertilizer and industrial uses.

Chemical properties: Ammonium nitrate (NH4NO3) is a crystalline salt that is highly soluble in water and hygroscopic. It is relatively stable under standard conditions but decomposes when heated and, under confinement with fuel or boosters, can act as an explosive oxidizer. The material is subject to strict storage and handling controls to prevent accidental detonation, contamination, or moisture-related caking.

Fertilizer applications: In agriculture, ammonium nitrate provides readily available nitrogen. It is often blended with phosphate and potassium fertilizers and offered in prilled or granular forms. Fertilizer-grade product contains minimal impurities to reduce risks, and quality standards vary by country.

Explosive uses: Ammonium nitrate-based explosives include formulations such as ammonium nitrate–fuel oil (ANFO) and various slurry or emulsion systems. These are selected for reliability, availability, and performance but are subject to rigorous regulation, licensing, and safety protocols to prevent misuse and accidental detonation.

Safety and regulation: Due to its oxidizing properties, ammonium nitrate requires secure storage away from fuels, reducing moisture, and limited access. Environmental concerns arise from potential nitrate leaching and waterway eutrophication in spills or improper disposal. Production and distribution are heavily regulated in most jurisdictions.

Production and history: Ammonium nitrate is produced by reacting ammonia with nitric acid, followed by purification and granulation. Its prominence as both a fertilizer and an industrial explosive component emerged in the 20th century.
