explosion
a chemical or mechanical action caused by combustion and accompanied by the creation of heat and he rapid expansion of gasses.
oxidizing agent
A substance that supplies oxygen to a chemical reaction
deflagration
a very rapid oxidation reaction accompanied by the generation of a low-intensity pressure wave that can disrupt the surroundings.
detonation
An extremely rapid oxidation reaction accompanied by a violent disruptive effect and an intense, high-speed shock wave.
low explosive
An explosive with a velocity of detonation less than 1,000 meters per second.
black powder
Normally, a mixture of potassium nitrate, carbon, and sulfur in the ratio 75/15/10.
safety fuse
A cord containing a core of black powder; used to carry a ?ame at a uniform rate to an explosive charge.
smokeless powder (single-base)
An explosive consisting of nitrocellulose.
smokeless powder (double-base)
An explosive consisting of a mixture of nitrocellulose and nitroglycerin.
high explosive
An explosive with a velocity of detonation greater than 1,000 meters per second.
primary explosive
A high explosive that is easily detonated by heat, shock, or friction
secondary explosive
A high explosive that is relatively insensitive to heat, shock, or friction.
detonating cord
A cord-like explosive containing a core of high-explosive material, usually PETN; also called primacord.
Gas-Air Mixtures
Another form of low explosive is created when a considerable quantity of natural gas escapes into a con?ned area and mixes with a sufficient amount of air.
TNT stands for
trinitrotoluene
PETN stands for
pentaerythritol tetranitrate
