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 nitric acid process produces nitric acid for use in making ammonium nitrate fertiliser. Using the Ostwald process, ammonia is vaporised and then oxidised over a 95% platinum and 5% rhodium catalyst at 930 °C (1,710 °F) and 6.5 bar (650 kPa) to form nitric oxide and superheated steam. The reaction gases are cooled to 38 °C (100 °F ...
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.
CF Industries Holdings, Inc. is an American manufacturer and distributor of agricultural fertilizers, including ammonia, urea, and ammonium nitrate products. The company is based in Northbrook, Illinois, a suburb of Chicago, [3] and was founded in 1946 as the Central Farmers Fertilizer Company.
The cause of the explosion was the ignition of ammonium nitrate used as raw material for fertilizer and explosives. Australia Taroom, Queensland August 30, 1972: 3 12 In the 1972 Taroom explosion, a truck carrying 12 tons of ammonium nitrate experienced an electrical fault and caught fire north of Taroom, Queensland. After the driver stopped ...
ANFO (/ ˈ æ n f oʊ / AN-foh) [1] (or AN/FO, for ammonium nitrate/fuel oil) is a widely used bulk industrial high explosive. It consists of 94% porous prilled ammonium nitrate (NH 4 NO 3 ) (AN), which acts as the oxidizing agent and absorbent for the fuel, and 6% number 2 fuel oil (FO). [ 2 ]
Fireworks and ammonium nitrate appear to have been the fuel that ignited a massive explosion that rocked the Lebanese capital of Beirut, experts and videos of the blast suggest.
The term "calcium ammonium nitrate" is applied to multiple different, but closely related formulations. One variety of calcium ammonium nitrate is made by adding powdered limestone to ammonium nitrate; [1] [2] another, fully water-soluble version, is a mixture of calcium nitrate and ammonium nitrate, which crystallizes as a hydrated double salt: [3] 5Ca(NO 3) 2 •NH 4 NO 3 •10H 2 O.
