Researchers have determined that ammonium nitrate explosion in West Texas, fertilizer plant last month sparked an explosion 14 people were killed and about 200 injured many reasons , a spokeswoman for the Texas State Fire Marshal 's office said Tuesday.
"Researchers have been able to narrow the origin to the point of contact of fertilizers and seeds , and we know what caused the explosion of ammonium nitrate , " Rachel Moreno , a spokeswoman for the Texas State Fire Marshal 's office said. "We do not know exactly why ."
Ammonium nitrate (NH4NO3) is a colorless, odorless , transparent crystals or white crystals , soluble in water , hygroscopic caking. Heat is easily decomposed ammonium , alkali decomposition case . Is an oxidizing agent , used in fertilizer and chemical raw materials .
Ammonium nitrate is also a dry fertilizer and other fertilizers such as phosphoric acid , and applied to the crop mix to promote economic growth . Under certain conditions it can be flammable and is used in the composition of Oklahoma City bombing in 1995 and the remaining 168 deaths .
Pure ammonium nitrate is a colorless , odorless , transparent crystals or white crystalline small particles , reacts with alkalis ammonia generation. Deliquescence , easy caking. Soluble in water, while endothermic , also soluble in acetone , ammonia , slightly soluble in ethanol, insoluble in ether.
Porous Prilled Ammonium Nitrate
is extremely insensitive explosives , more insensitive than the safety of explosives c4. An industrial 8 # detonator ( detonating c4 just use 6 on it ) are not sufficient to detonate a mixture of ammonium nitrate sensitizer
. Ammonium nitrate is the hardest detonate explosives , impact sensitivity is : 50kg hammer drop height 50cm , 0% explosion. Compared to the famous explosive nitroglycerine 200g hammer , 20cm drop height , 100% sensitivity explosive , ammonium nitrate visible insensitive . Once dissolved in water and ammonium nitrate , detonation sensitivity is greatly reduced , is simply impossible human impact detonated .
Mainly used as fertilizer and industrial and military explosives. Can be used in insecticides , refrigerants, nitrogen oxide absorber, manufactured nitrous oxide , pyrotechnics .
Spot analysis iridium. Oxidants. Catalyst. Refrigerant. Preparation of nitrous oxide ( laughing gas ) . Manufacturing fireworks and explosives. Used as fertilizer in agriculture , about 34% of the total nitrogen content , there are fast-acting fertilizer known. Used extensively for the manufacture of smokeless powder . The chemical industry for the manufacture of nitrous oxide , pharmaceutical vitamin B. E-glass light manufacturing .
