Initiation of a military explosive (or propellant) to deflagration, explosion or detonation can be achieved either by ignition or by detonation. Ignition method is used for producing deflagration (See Vol 3, p D38-R)(Ref 48), such as in case of propellants and some low demolition explosives, while detonation method (See in this Vol,p D137ff) is used for... 

These igniters, known also as lighters, are used for igniting safety fuses". Some are known in the US as "Bickford Fuses "(See Vol 3 of Encycl, p B112-L) and serve to initiate certain demolition explosives (See Vol 3 of Encycl, p D56-R)...

WWII. RDX or Cyclonite. See 1899. Cyclo-trimethylenetrinitramine WWII. Demolition Explosives. Wide use was made in demolition practice of shaped charges, which utilize the Munroe-Neumann Effect, described in Vol 4 of Encycl, pp D442 to D443. 

Other liquid combustibles, such as petroleum, benzene, toluene, etc, were proposed, but Turpin preferred carbon bisulfide. Pan clastic es were successfully used in Belgium as military demolition explosives and in Germany they were tried for loading projectiles. For this two glass containers with thin walls were used. One was filled with NOa and die other with CO2. They were placed inside the projectile, one on top of the other, and in ordet to prevent premature breakage, several rubber cubes were inserted between the walls of projectiles and glass containers.

Between World War I and II, TNT replaced picric acid as the explosive of choice in munitions. It was also mixed with other compounds to produce more powerful explosives with unique characteristics. Amatol is a mixture containing between 40% and 80% ammonium nitrate and TNT. Pentolite is a mixture of PETN (pentaerythritol tetranitrate) and TNT. Another common explosive mixture is RDX (cyclotrimethylenetrinitramine) and TNT. RDX is an abbreviation for Royal Demolition Explosive. 

In destruction by detonation each dud is placed with its fuze towards, and as near as possible, to the demolition explosive which will be detonated by means of a blasting cap (electric or nonelectric). If a barricade is not available in immediate vicinity, all personnel should be removed to a safe distance, before the demolition charge is fired... 

A "Special Demolition Explosive developed by Trojan Powder Co of Allentown, Pennsylvania and standardized shortly before WWII was based on NS (Nitrostarch) instead of NG- Its compn and properties are given in Ref 52, p207 Ref 66, p7—85 and in Vol 3 of Encycl under Ref 12, listed on p D60-R. Trojan demolition explosives were tested at Picatinny Arsenal by J.D. Hopper and covered by PATR s 782(1936), 848(1937), 864 (1937) and 957(1939)...

At the beginning of World War II nitrostarch explosives were used for filling bombs, but this practice ceased when the output of trinitrotoluene reached adequate volume. Serious interest was roused, on the other hand, in Trojan s Nitrostarch Demolition Explosive. Its composition is reported in Vol. IH. 

Constituents. The military use a range of chemicals such as explosives and propellants that are sometimes termed energetic molecules, Generally speaking, modern explosives are cyclic, often heterocyclic, composed of carbon, nitrogen and oxygen, eg 2,4,6-trinitrotoluene RDX (Royal Demolition explosive hexahydro-1,3,5-trinitro-l, 2,3-triazine) HMX (High...

Demolition Explosives (Demolition Blocks, Demolition Charges and,Demolition Devices) (See also Demolition Hoses, Demolition Kits and Demolition Snakes). Demolition expls are those used for demolition purposes. They are mostly HE s (such as TNT, PA, Tetryl, FETN, Dynamite, etc), made in the shape of blocks, cartridges, etc. Some LE s, such as compressed wet Guncotton, can also be used. Under the term Demolition Devices, Ohart (Ref 8) described Bangalore Torpedoes (See Vol 2, P 16"R of this Encycl) and various demolition blocks, including shaped charges. In Ref 12a, the same devices are listed as Demolition Materials (qv)...
