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

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

Low explosives are a type of explosive that deflagrates (burns) rather than detonating. Examples include gunpowder, smokeless powder, and flash powder.

High Explosives

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

Explosives are used in a variety of applications including mining, demolition, military uses, fireworks, and propulsion.

Safety and Handling

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.
