deflagrants

Deflagrants are a class of pyrotechnic compositions that burn very rapidly. This rapid burning, known as deflagration, produces a large volume of gas and heat in a short period of time. Unlike detonation, which is a supersonic shock wave, deflagration is a subsonic combustion process.

The term deflagrant is often used in the context of explosives, but it is important to distinguish deflagration from detonation. Many substances that deflagrate can be used as propellants in firearms or rockets, where controlled burning is desired. In contrast, detonating explosives are used for their shattering effect.

Common examples of deflagrants include gunpowder, which is a mixture of potassium nitrate, charcoal, and sulfur, and various smokeless powders used in ammunition. These materials are designed to burn quickly but without the explosive force of a detonating agent. The rate of deflagration can be influenced by factors such as particle size, confinement, and the chemical composition of the mixture. Understanding the properties of deflagrants is crucial in the design and safe handling of pyrotechnic devices and propellants.
