explosive

explosive,

substance that undergoes decomposition or combustion with great rapidity, evolving much heat and producing a large volume of gas. The reaction products fill a much greater volume than that occupied by the original material and exert an enormous pressure, which can be used for blasting and for propelling.

Classification of Explosives

Chemical explosives can be classified as low or high explosives. Low (or deflagrating) explosives are used primarily for propelling; they are mixtures of readily combustible substances (e.g., gunpowder) that when set off (by ignition) undergo rapid combustion. High (or detonating) explosives (e.g., TNT) are used mainly for shattering; they are unstable molecules that can undergo explosive decomposition without any external source of oxygen and in which the chemical reaction produces rapid shock waves. Important explosives include trinitrotoluenetrinitrotoluene

Applications of Explosives

The major use of explosives has been in warfare. High explosives have been used in bombs, explosive shells, torpedoes, and missile warheads. Nondetonating explosives, e.g., gunpowder and the smokeless powders, have found extensive use as propellants for bullets and artillery shells.

The most important peaceful use of detonating explosives is to break rocks in mining. A hole is drilled in the rock and filled with any of a variety of high explosives; the high explosive is then detonated, either electrically or with a special high-explosive cord. Special explosives, called permissible explosives, must be used in coal mines. These explosives produce little or no flame and explode at low temperatures to prevent secondary explosions of mine gases (see dampdamp,
in mining, any mixture of gases in an underground mine, especially oxygen-deficient or noxious gases. The term damp probably is derived from the German dampf, meaning fog or vapor. Several distinct types of damp are recognized.

Development of Nondetonating Explosives

Until the 19th cent. gunpowder was widely used in most types of firearms. The invention of various smokeless powders led to the ultimate replacement of gunpowder as a propellant in rifles and guns. Probably the first successful smokeless powder was made by Edward Schultze, a Prussian artillery captain, c.1864. After 1870 it was known as Schultze powder. Its rate of burning was less than that of guncotton because of the partial gelatinization of the powder by a mixture of ether and alcohol; however, it still burned too rapidly for use in rifles. Schultze powder is used in shotguns, blank cartridges, and hand grenades and in igniting the dense, propellant powder used in artillery. The main constituent of Schultze powder is nitrocellulose.

About 1885 a smokeless powder suitable for rifled guns appeared. Invented by Paul Vieille, it was called poudre B and was made from nitrocotton and ether-alcohol. Subsequently, Alfred NobelNobel, Alfred Bernhard
, 1833–96, Swedish chemist and inventor. Educated in St. Petersburg, Russia, he traveled as a youth and returned to St. Petersburg in 1852 to assist his father in the development of torpedoes and mines.

In Ballistite two of the most powerful explosives known at the time were united; it is made from nitrocotton (with a low nitrogen content) gelatinized by nitroglycerin. Another smokeless powder, cordite, was invented by Sir Frederick Augustus Abel and Sir James Dewar in 1889; it contained a highly nitrated guncotton and nitroglycerin blended by means of acetone. Mineral jelly was added to act as a lubricant. Indurite, invented by Charles E. Monroe in 1891, is made from guncotton and is colloided with nitrobenzine; washing with methyl alcohol frees the lower nitrates from the guncotton.

explosive

[ik′splō·siv] (materials) A substance, such as trinitrotoluene, or a mixture, such as gunpowder, that is characterized by chemical stability but may be made to undergo rapid chemical change without an outside source of oxygen, whereupon it produces a large quantity of energy generally accompanied by the evolution of hot gases.

explosive

Any explosive chemical compound, mixture, or device, the primary or common purpose of which is to produce an explosion; i.e., with substantially instantaneous release of gas and heat, unless such compound, mixture, or device is otherwise specifically classified by the US Department of Transportation. Class A: possessing detonating hazard, such as dynamite or nitroglycerin. Class B: possessing flammable hazard, such as propellant explosives. Class C: containing class A or class B explosives, but in restricted quantities.
