Editing Azide (section)

=== Primary explosives and propellants===
[[Sodium azide]] {{chem2|NaN3}} is the propellant in automobile [[airbag]]s. It decomposes on heating to give nitrogen gas, which is used to quickly expand the air bag:<ref name=Ullmann/>

:{{chem2|2 NaN3 → 2 Na + 3 N2}}

Heavy metal azides, such as [[lead azide]], {{chem2|Pb(N3)2}}, are shock-sensitive [[detonator]]s which violently decompose to the corresponding metal and nitrogen, for example:<ref>{{cite book |last1=Shriver |last2=Atkins |title=Inorganic Chemistry |edition=5th |publisher= W. H. Freeman and Company |location=New York |page=382}}</ref>

:{{chem2|Pb(N3)2 → Pb + 3 N2}}

[[Silver azide]] {{chem2|AgN3}} and [[barium azide]] {{chem2|Ba(N3)2}} are used similarly.

Some organic azides are potential [[Rocket propellant|rocket propellants]], an example being [[2-Dimethylaminoethylazide|2-dimethylaminoethylazide]] (DMAZ) {{chem2|(CH3)2NCH2CH2N3}}.
