räjähtävät

Räjähtävät is a Finnish term that can function as an adjective meaning explosive and as a verb form meaning they explode. In Finnish, räjähtävä describes materials or devices that release energy rapidly and generate a shock wave; räjähtävät can modify plural nouns or be used as the third-person plural form of räjähtää, meaning they explode.

In science and industry, explosives are energetic materials that rapidly convert chemical energy to gas and heat, producing high-pressure waves. The Finnish term räjähtävät is used in texts to refer to explosive substances (räjähtävät aineet) or devices (räjähtävät laitteet).

Classification and properties: Explosives are categorized by sensitivity and velocity of detonation. Primary explosives are highly sensitive and used to initiate detonation; secondary explosives are less sensitive and form the main charge. Other categories include blasting agents, propellants, and pyrotechnic compositions. Common examples include general categories; however, listing specific instructions is not appropriate.

Applications and safety: Explosives are used in mining, quarrying, construction, demolition, and some military contexts, subject to strict regulation. Handling, storage, transportation, and use require licenses, safety procedures, and compliance with national laws. In civilian contexts, non-explosive alternatives may be preferred to reduce risk.

Etymology and usage: The term comes from Finnish räjähtää, to explode; räjähtävä (explosive) and räjähtävät (explosive plural or they explode) reflect words' root. In Finnish-language scientific and industrial writing, räjähtävät commonly appears as an adjective or noun phrase to denote explosive materials or devices.
