A detonator is a device used to trigger an explosive device. Detonators can be chemically, mechanically, or electrically initiated, the latter two being the most common. Explosive Ordnance Devices or EOD (hand grenades, naval mines etc.) generally use mechanical detonators. Image File history File links Broom_icon. ...

A weapons cache is detonated at the East River Range on Bagram Airfield, Afghanistan Detonation is a process of supersonic combustion in which a shock wave is propagated forward due to energy release in a reaction zone behind it. ... Explosive devices, as used by terrorists, guerrillas or commando forces, are formally known as Improvised Explosive Devices or IEDs. ... For other uses, see Bomb (disambiguation). ...

The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has been crimped. Many detonators' primary explosive is a material called ASA compound. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators. In an explosive, pyrotechnic device or military munition, a fuse (or fuze) is the part of the device that initiates function. ... Crimping is joining two pieces of metal or other malleable material by deforming one or both of them to hold the other. ... A primary explosive is an explosive that is extremely sensitive to stimuli such as impact, friction, thermal, or electrostatic sources of initiation. ... Lead azide (Pb(N3)2) is an explosive and toxic crystalline compound. ... Lead styphnate (lead 2,4,6-trinitroresorcinate, (C6HN3O8)Pb), whose name is derived from styphnic acid, is a toxic explosive used as a component in primer and detonator mixtures for less sensitive explosives, such as nitroglycerine. ...

Other materials such as DDNP (diazo dinitro phenol) are also used as the primary charge to reduce the amount of lead emitted into the atmosphere by mining and quarrying operations. Old detonators used mercury fulminate as the primary, and it was often mixed with potassium chlorate to yield better performance. This article is about mineral extractions. ...

Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the chemical formula KClO3. ...

Electrical detonators

There are three categories of electrical detonators: instantaneous electrical detonators (IED), short period delay detonators (SPD) and long period delay detonators (LPD). SPDs are measured in milliseconds and LPDs are measured in seconds.

In situations where nanosecond accuracy is required, specifically in the implosion charges in nuclear weapons, exploding-bridgewire detonators are employed. They contain no explosive on their own, instead the shock wave is created by vaporizing a length of a thin wire by an electric discharge. The mushroom cloud of the atomic bombing of Nagasaki, Japan, 1945, rose some 18 kilometers (11 mi) above the hypocenter A nuclear weapon derives its destructive force from nuclear reactions of fusion or fission. ... The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) was invented by Luis Alvarez and Lawrence Johnston for the Fat Man-type bombs of the Manhattan Project, during their work in Los Alamos National Laboratory. ... a localised surplus of electrons migrates from the negative pole to the positive pole to overcome its unfavourable energetic condition. ...

A new development is a slapper detonator, which uses thin plates accelerated by an electrically exploded wire or foil to deliver the initial shock. It is in use in some modern weapon systems. A variant of this concept is used in mining operations, when the foil is exploded by a laser pulse delivered to the foil by optical fiber. A slapper detonator is a relatively recent kind of a detonator developed in Lawrence Livermore National Laboratory. ... For other uses, see Laser (disambiguation). ... Optical fibers An optical fiber (or fibre) is a glass or plastic fiber designed to guide light along its length. ...

Non-electric detonators

Non-electric detonators usually take the form of an ignition-based explosive. Whilst they are mainly used in commercial operations, non-electric detonators are still used in military operations. This form of detonator is most commonly initiated using safety fuse, and used in non time-critical detonations i.e. Conventional Munitions Disposal In an explosive, pyrotechnic device or military munition, a fuse (or fuze) is the part of the device that initiates function. ...
