Safety Profile
Explodes when heated above 270°C or on impact. Pure silver azide explodes at 340℃. An electric field or irradiation by electron pulses can explode the crystals. Shock-sensitive when dry and has detonated @ 250℃. Solutions in aqueous ammonia explode above 100°C. Reacts to form more explosive products with iodine (forms iodine azide); bromine and other halogens. The presence of metal oxides or metal sulfides increases the azide's sensitivity to explosion. lMixtures with sulfur dioxide are explosive. When heated to decomposition it emits toxic fumes of NOx.
