kõrgeplahvatuslikeks

Kõrgeplahvatuslikeks is an Estonian term that translates to "high explosives." This designation refers to a class of explosive materials characterized by their rapid decomposition and the generation of a significant amount of energy in a very short period. Unlike low explosives, which burn rapidly, high explosives detonate, creating a supersonic shock wave that propagates through the material. This detonation process results in a much more powerful and destructive effect.

The primary distinction between high and low explosives lies in their detonation velocities. High explosives typically have detonation velocities exceeding 1,000 meters per second, with many exceeding 5,000 meters per second. This rapid energy release is what makes them suitable for applications such as mining, demolition, and military ordnance. Examples of common high explosives include TNT (trinitrotoluene), RDX (cyclotrimethylenetrinitramine), and PETN (pentaerythritol tetranitrate).

The sensitivity of high explosives varies. Some, like PETN, are relatively sensitive and can be detonated by friction or impact, while others, such as TNT, are more stable and require a detonator to initiate their explosion. The development and use of high explosives are subject to strict regulations due to their inherent dangers and potential for misuse. Their study and application fall under the fields of chemistry, physics, and engineering, focusing on understanding their properties, safe handling, and effective utilization.
