Basic Information

Molecular Structure:
CAS No.:	13863-88-2
Name:	Silver azide
Article Data:	58

Formula:	AgN3
Molecular Weight:	149.888
Synonyms:	Silverazide; Silver monoazide; Silver(1+) azide
Density:	g/cm³
Melting Point:	212°C
Boiling Point:	°Cat760mmHg
Flash Point:	°C
Solubility:	0.01g/100mL H2O (100°C) [CRC10]
Safety:	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°C. 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. Mixtures with sulfur dioxide are explosive. When heated to decomposition it emits toxic fumes of NO_x. See also AZIDES and SILVER COMPOUNDS.
