Explosive
Explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.
An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. An explosion creates a shock wave.
Types of Explosives[edit]
There are two types of explosives: low explosives and high explosives. Low explosives, or propellants, burn at subsonic speeds. High explosives detonate at supersonic speeds.
Low Explosives[edit]
Low explosives are a type of explosive that deflagrates (burns) rather than detonating. Examples include gunpowder, smokeless powder, and flash powder.
High Explosives[edit]
High explosives, upon initiation, function by detonation, a rapid decomposition (explosion) of the material caused by a shock wave moving through the product at a rate faster than the speed of sound. Examples include dynamite, C-4, and TNT.
Uses of Explosives[edit]
Explosives are used in a variety of applications including mining, demolition, military uses, fireworks, and propulsion.
Safety and Handling[edit]
Handling explosives can be dangerous, especially if the explosive is accidentally detonated. Proper safety measures, including the use of PPE, should be taken when handling explosives.
