Knowra Silver azide Silver azide Silver azide (AgN₃) is an inorganic salt made of silver cations and azide anions. It forms highly sensitive explosive crystals used in detonators and studied for its solid-state properties.
Azide ion : The linear polyatomic anion N₃⁻, whose resonance-stabilized bonding gives azides distinctive chemical properties. These anions pair with silver ions to form the compound’s crystal lattice.
Explosive train : A sequence of energetic components that transfers initiation from a trigger to a main explosive charge. Silver azide can serve near the beginning of this chain as an initiating charge.
Silver : A metallic chemical element with symbol Ag and atomic number 47. Silver cations form the positive component of silver azide’s ionic compound.
Silver nitrate : The soluble silver salt AgNO₃, used in analytical chemistry, photography, and the preparation of other silver compounds. It contains the same metal but nitrate rather than azide, so it does not share silver azide’s explosive behavior.
Silver azide crystal structure : The ordered arrangement of silver and azide ions in crystalline AgN₃. Its lattice is a central subject of solid-state studies of silver azide.
Blasting cap : A compact initiating device used to set off a larger explosive charge. Silver azide has been used in initiating compositions for this type of device.
Nitrogen : A chemical element with symbol N and atomic number 7, occurring commonly as diatomic gas. Three nitrogen atoms form each azide ion in AgN₃.
Silver nitride : An unstable silver–nitrogen compound distinct from the azide salt AgN₃. The similar name can obscure that silver nitride and silver azide have different compositions and structures.
Explosive decomposition : A rapid chemical breakdown that releases energy and gaseous products, producing an explosive pressure rise. Silver azide decomposes rapidly under initiation, generating heat and nitrogen gas.
Lead azide : A primary explosive, Pb(N₃)₂, widely used in detonators because it is sensitive and initiates reliably. It serves similar initiating roles but is generally preferred over silver azide in practice.
