Räjähdysaineena

Räjähdysaineena refers to the use of explosives in Finnish. It encompasses the properties, manufacture, handling, and application of explosive materials. Explosives are substances or devices that can undergo rapid chemical decomposition, producing a large volume of gas and a sudden release of energy, resulting in a high-pressure wave.

The primary characteristic of an explosive is its rapid rate of decomposition, which distinguishes it from propellants that burn more slowly. This rapid reaction generates heat and gas, leading to a detonation or deflagration. The energy released can be used for various purposes, including mining, construction, demolition, and in military applications such as ordnance.

Explosive materials are broadly classified into primary explosives and secondary explosives. Primary explosives are highly sensitive to shock, friction, or heat and are used in small quantities to initiate less sensitive secondary explosives. Secondary explosives are less sensitive but release significantly more energy upon detonation.

The safe handling and use of explosives require specialized knowledge and adherence to strict regulations due to their inherent dangers. This includes proper storage, transportation, and the precise application of explosive charges to achieve desired outcomes while minimizing risks to personnel and the environment. The study and application of explosives fall under the field of explosives engineering and technology.
