Räjäytysaineet

Räjäytysaineet, or explosives, are chemical compounds or mixtures that can undergo rapid decomposition, producing a large volume of gas and a sudden release of energy. This energy release manifests as a shock wave and heat, creating a powerful explosion. Explosives are broadly categorized into two main types: high explosives and low explosives.

High explosives detonate, meaning they propagate a detonation wave through the material at supersonic speeds. Examples include dynamite, TNT, and nitroglycerin. These are used for demolition, mining, and in military applications for their destructive power.

Low explosives deflagrate, meaning they burn very rapidly, producing gas and heat but at subsonic speeds. Gunpowder is a classic example. Low explosives are used in firearms as propellants and in pyrotechnics for fireworks.

The production and use of explosives are strictly regulated in most countries due to their inherent dangers and potential for misuse. They require specialized knowledge and training for safe handling, storage, and application. The chemical composition and physical properties of an explosive determine its sensitivity to initiation, its power, and its brisance (shattering effect). The development of explosives has had a significant impact on fields ranging from construction and resource extraction to warfare and scientific research.
