Pb(N3)2

High explosive, readily initiated. Used as a primary explosive in detonators.
Reacts instantly from moderate levels of F.I.S.H. to full velocity detonation.

Lead azide is highly sensitive and usually handled and stored under water in insulated rubber containers. It will explode after a fall of around 150 mm.

Lead Azide is a white to buff coloured granular substance although it is often mixed with graphite to reduce friction sensitivity making it dark gey to black in appearance

Lead Azide is the most common primary explosive used in detonators although Lead Styphnate has also been used.
