Explosives

Explosives are reactive substances that contain a large amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances.

History[edit | edit source]

The discovery of gunpowder and the invention of the steam engine sparked a slow advancement in the science of explosives. These advancements were minor compared to the impact of WWI and WWII, which saw the development of high explosives, dynamite and other munitions, a trend that continues to this day.

Types of Explosives[edit | edit source]

Explosives are categorized as high or low explosives. High explosives detonate to produce a defining supersonic over-pressurization shock wave. Examples of high explosives include TNT, C-4, semtex, nitroglycerin, dynamite, and HMX. Low explosives deflagrate at subsonic speeds. Examples include gunpowder, smokeless powder, and flash powder.

Safety and Handling[edit | edit source]

The handling of explosives involves great risk, and is subject to strict laws and regulations. From a safety standpoint, the most important variables in the handling of explosives are stability, sensitivity, and briscance.
