In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
Dynamite is moderately sensitive to shock. Shock resistance tests are usually carried out with a drop-hammer: about 100 mg of explosive is placed on an anvil, upon which a weight of between 0.5 and 10 kg (1 and 22 lb) is dropped from different heights until detonation is achieved. [ 9 ]
Binary explosives are cap-sensitive (detonatable with a standard #8 blasting cap) two-part explosives mixtures, shipped separately and combined at the use site. Many of these mixtures are based on Ammonium nitrate as an oxidizer plus a volatile fuel, but unlike ANFO (ammonium nitrate fuel oil explosive) these binaries can be detonated by ...
For example, dynamite is a mixture of highly sensitive nitroglycerin with sawdust, powdered silica, or most commonly diatomaceous earth, which act as stabilizers. Plastics and polymers may be added to bind powders of explosive compounds; waxes may be incorporated to make them safer to handle; aluminium powder may be introduced to increase total ...
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...

With the increased safety of the black powder substitutes often comes a reduced sensitivity to ignition. Flintlocks in particular need very sensitive, finely granulated powder for use in the flash pan, and black powder tends to perform more reliably in these and traditional caplock guns than substitutes. Modern in-line muzzleloaders provide a ...
RDX (abbreviation of "Research Department eXplosive" or Royal Demolition eXplosive) or hexogen, [4] among other names, is an organic compound with the formula (CH 2 N 2 O 2) 3.It is white, odorless, and tasteless, widely used as an explosive. [5]
