    Overview of Explosives

    • Explosives are reactive substances that contain potential energy that can produce an explosion if released suddenly.
    • An explosive charge is a measured quantity of explosive material, which may consist of one or more substances.
    • Explosive materials may be categorized by the speed at which they expand and their sensitivity to heat or pressure.
    • High explosives detonate, while low explosives deflagrate.
    • Primary explosives are sensitive and can be initiated by a relatively small amount of heat or pressure, while secondary or tertiary explosives are relatively insensitive.
    • A wide variety of chemicals can explode, but only some are manufactured specifically for use as explosives.
    • The largest commercial application of explosives is in mining, using nitrate-based explosives such as ANFO and emulsions of fuel oil and ammonium nitrate.
    • Explosives are also used in cladding (explosion welding) in materials science and engineering.
    • The history of chemical explosives began with the invention of gunpowder by Chinese alchemists in 1044.
    • Nitroglycerin was the first useful explosive stronger than black powder, followed by TNT, dynamite, and gelignite.
    • World War I saw the adoption of TNT in artillery shells, and World War II saw extensive use of new explosives.
    • More powerful explosives such as C-4 and PETN have largely replaced earlier explosives, but they are waterproof and malleable, and react with metal, making them useful for some applications.
