Lithium azide is the lithium salt of hydrazoic acid. It is an unstable and toxic compound that decomposes into lithium and nitrogen when heated.

Preparation

It can be prepared by metathesis reaction between sodium azide and lithium nitrate:

NaN3 + LiNO3 → LiN3 + NaNO3

or lithium sulfate solutions:

2 NaN3 + Li2SO4 → 2 LiN3 + Na2SO4[2]
