Barium azide Ba(N3)2 is an inorganic azide, is explosive, but less sensitive to mechanical shock than lead azide.
Uses
Can be used to make azides of magnesium (but its hydrolytic tendency frustrated efforts to isolate it), sodium, potassium, lithium, rubidium and zinc with their respective sulfates.[4]
- Ba(N3)2 + Li2SO4 → 2 LiN3 + BaSO4
It can also be used in the preparation of extra pure nitrogen on heating:
- Ba(N3)2 → Ba + 3 N2
