a material like dynamite, TNT, PETN composition being -- it requires -- that requires only an initiating system to explode it
a material which is one which will detonate, and it has extremely high speeds and high reaction rates
An energetic material that detonates (instead of deflagrating or burning); the rate of advance of the reaction zone into the unreacted material exceeds the velocity of sound in the unreacted material.
A material that is capable of sustaining a reaction front that moves through the unreached material at a speed equal to or greater than that of sound in the medium (typically 3300 ft/sec (1000 m/sec); a material capable of sustaining a detonation. (See also Detonation.)
Any explosive with a velocity of detonation greater than 1000 meters per second. Dynamite is a high explosive.
An explosive with a rapid burning rate. On detonation, a high explosive will have a shattering effect on objects in the immediate area. TNT, RDX, nitroglycerin, dynamite, pentaerythritoltetranitrate, and various plastic explosives are types of high explosives.
