Lead azide (Pb(N3)2) is an inorganic compound. More so than other azides, Pb(N3)2  [resaltar:60l1d3f6]is explosive[/resaltar:60l1d3f6]. It is used in detonators  to initiate secondary explosives. In a commercially usable form, it is a white-to-buff powder.
Preparation and handling

Lead azide is prepared by metathesis between sodium azide and lead nitrate. Dextrin can be added to the solution to stabilize the precipitated product. The solid is not very hygroscopic, and water does not reduce its impact sensitivity. It is normally shipped in a dextrinated solution that lowers its sensitivity. When protected from humidity, it is completely stable in storage.[2]
[edit] [resaltar:60l1d3f6]Explosive characteristics[/resaltar:60l1d3f6]
[resaltar:60l1d3f6]Lead azide is highly sensitive[/resaltar:60l1d3f6] and usually handled and stored under water in insulated rubber containers.[resaltar:60l1d3f6]It will explode after a fall of around 150 mm (6 in) or in the presence of a static discharge of 7 millijoules. Its detonation velocity is around 5.18 km/s (17,500 ft/s).[/resaltar:60l1d3f6]

Ammonium acetate and sodium dichromate are used to destroy small quantities of lead azide.

Lead azide reacts with copper, zinc, cadmium, or alloys containing these metals to form other azides. For example, copper azide is even more explosive and too sensitive to be used commercially. Sodium azide is used both for the manufacture of lead azide and as preservative and diluent, which can lead to problems.

Por lo que dice el mismo articulo que citas, que debe guardarse bajo el agua en recipientes de goma por su reactividad con metales y alta sensibilidad. pareceria dificil que se use dentro de un proyectil.

era tetraetilo de plomo
"t used to be that before the addition of lead, gasoline tended to pre-ignite or detonate, causing a metallic 'pinging' sound, a situation called engine-knocking, that damaged the engine. [resaltar:2ylibrrx]Tetraethyl leaded[/resaltar:2ylibrrx] gasoline changed that. Not only did leaded gasoline withstand higher compression environments, they also lubricated the inside and valves of the engine, protecting the valve seats from erosion. "
