UsesEdit

Copper azide is very explosive and is too sensitive for any practical use unless handled in solution.

PreparationEdit

Copper azide can be prepared by a metathesis reaction between water-soluble sources of Cu2+ and azide ions. (Spectator ions omitted in reaction below).

Cu2+ + 2 N3 → Cu(N3)2

It can be destroyed by concentrated nitric acid to form non-explosive products, these being nitrogen, nitrogen oxides and copper(II) nitrate.
