Spontaneous combustion
From Free net encyclopedia
Spontaneous combustion can have several meanings:
- The self-ignition, or apparent self-ignition, and burning of any mass; often of highly flammable materials, such as a pile of oily rags; see combustion.
- Spontaneous human combustion is the alleged phenomenon of a human being suddenly bursting into flames.
- Pyrophoric materials can ignite spontaneously under certain conditions:
- Some alloys, such as ferrocerium for lighter "flints" and the hardened depleted uranium used in anti-armor weapons, have a low ignition temperature when finely divided. Scraping such an alloy tends to create a large number of sparks, and pulverizing it can lead to a fierce metal fire.
- Other substances such as caesium, rubidium or silanes can ignite spontaneously when contacting air. See pyrophoricity.
