Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
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 steam.In an ideal stoichiometrically balanced reaction, ANFO is composed of about 94.5% AN and 5.5% FO by weight.
Many efforts have been made to improve the Haber–Bosch process. Many metals were tested as catalysts. The requirement for suitability is the dissociative adsorption of nitrogen (i. e. the nitrogen molecule must be split into nitrogen atoms upon adsorption). If the binding of the nitrogen is too strong, the catalyst is blocked and the ...
The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30 °C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) known as UN32 or UN-32, which consists of 45% ammonium nitrate, 35% urea and only 20% water. Other ...
Ammonium compounds are used not only for fertilisers, but also explosives. Billingham-on-Tees was a small village in 1917, when its Grange Farm was chosen to be the site of a large chemical works. On 22 March 1918, the Minister of Munitions approved the site to be developed as a factory that would make ammonium nitrate. [1]
It is a mainstay of the modern chemical industry and provides the raw material for the most common type of fertilizer production, globally (for example, ammonium nitrate, a common fertilizer, is made by reacting ammonia with nitric acid).
Another fertilizer giant, Uralchem, founded by sanctioned billionaire Dmitry Mazepin, provided Sverdlov more than 27,000 metric tons of ammonium nitrate, the railway data showed. Ammonium nitrate ...
Ammonal is an explosive made up of ammonium nitrate and aluminium powder. TNT is added to create T-ammonal which improves properties such as brisance. The mixture is often referred to as Tannerite, which is a brand of ammonal. The ammonium nitrate functions as an oxidizer and the aluminium as fuel.
