Ammonium nitrate is an ammonium salt, NH4NO3, which is a colorless and odorless transparent crystal or white crystal. Very soluble in water, easy to absorb moisture and agglomerate, and absorb a lot of heat when dissolved. Explosive decomposition caused by violent impact or heating, and alkali decomposition. It is an oxidant used in fertilizers and chemical raw materials.
Pure ammonium nitrate is a colorless and odorless transparent crystal or small white crystal, which reacts with alkali to generate ammonia and absorb heat. Easily deliquescent and caking. Soluble in water, while absorbing heat, but also soluble in acetone and ammonia, slightly soluble in ethanol, insoluble in ether.
Mainly used as fertilizer and industrial and military explosives. It can also be used as insecticide, refrigerant, nitrogen oxide absorbent, laughing gas, fireworks and so on.
Iridium, oxidant, catalyst and refrigerant are analyzed bit by bit to make nitrous oxide (nitrous oxide), fireworks and explosives, which are used as fertilizers in agriculture. The total nitrogen content is about 34%, which is called quick-acting fertilizer. It is widely used to make smokeless gunpowder, nitrous oxide and medical vitamin B in chemical industry, and alkali-free glass in light industry.
