Nitroglycerin mixture, desensitized, solid

Individual chemicals may be so prepared or mixed to be suitable for use as either deflagrating or detonating explosives. Explosives find wide use as mining and constmction to blast ore, coal, and rock in petroleum prospecting and oil well production in manufacturing to bond metals and manufacture diamonds as pyrotechnics and in the aerospace Industry. Military explosives are used in demolition, ammunition, pyrotechnics, signals, and the like. 

In transportation terms, explosives are divided into six divisions (1.1 to 1.6) based on the (1) speed with which they react (2) sensitivity and modes of initiation (3) explosive power and (4) effects of the packaging or article to contain the explosive. 

Explosives are further assigned to one of thirteen compatibility groups (A through H, J, K, L, N, S) which identify the explosive article or substance and allow identification of other compatible explosives. 

A large number of chemicals, usually organic compounds of carbon, hydrogen, nitrogen, and oxygen, exhibit explosive properties  

Smokeless powders, solid low explosives, are virtually smokeless in comparison to black powder. They are also less susceptible to damp, store better, are more powerful, and bum at a more easily controlled rate. These benefits come with the disadvantage that they bum hotter and cause greater damage to the barrels of weapons in which they are used extensively as ammunition propellants. The length of a weapon s barrel and other ballistic requirements result in smokeless powder for pistol ammunition being in flakes, which bums quickly, while slower burning balls, cylinders, or tubes are used for rifle ammunition riflepowder). There are three types of smokeless powder
