Barium azide is an inorganic azide with the formula . It is a barium salt of hydrazoic acid. Like all azides, it is explosive. It is less sensitive to mechanical shock than lead azide.

Preparation

Barium azide may be prepared by reacting sodium azide with a soluble barium salt: :

Uses

Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. :

It can also be used as a source for high purity nitrogen by heating: :

This reaction liberates metallic barium, which is used as a getter in vacuum applications.
