An explosive booster acts as a bridge between a low energy explosive and a low sensitivity (but typically high energy) explosive. An explosive material is a material that either is chemically or otherwise Energetically unstable or produces a sudden expansion of the material usually accompanied It increases the energy of an initiating explosive to the degree sufficient to trigger the secondary charge.
For example: An initiator (such as shock tube, or cannon fuse) does not have the energy to trigger large high explosive charges (such as PETN, TNT, or ANFO), so a booster is used to upgrade the energy so that the main charge is activated. A shock tube is a device used primarily to study gas phase Combustion reactions In an Explosive, Pyrotechnic device or military Munition, a fuse (or fuze) is the part of the device that initiates function Pentaerythritol tetranitrate ( PETN, also known as pentrite, or rarely and primarily in German as nitropenta) is one of the most powerful high explosives Trinitrotoluene ( TNT) is a Chemical compound with the formula C6H2(NO23CH3 ANFO (or AN/FO, for ammonium nitrate / fuel oil) is a widely used Explosive mixture Tetryl was once a very popular chemical for booster charges, particularly during World War II, but has been largely superseded by other compositions. Tetryl is a sensitive Explosive compound used to make Detonators and Explosive booster charges World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including
Explosive boosters are typically constructed by mixing high sensitivity and high energy compounds at various ratios.
When encountered in connection with artillery shells or air dropped bombs, such a device is called gayne. See detonators. For the Ratt album see Detonator (album A detonator is a device used to trigger an Explosive device.
