Decomposition of Ammonium Nitrate

NH4NO3 → N2O + 2H2O

概要

Ammonium nitrate decomposes at about 200 C to form nitrous oxide (laughing gas) and water. At higher temperatures or with confinement, it can decompose explosively to nitrogen, oxygen, and water. The dual nature of ammonium nitrate as both a fertilizer and explosive makes it a significant safety concern.
