Ferrocerium is used in fire lighting in conjunction with a striker, similarly to natural flint-and-steel, though ferrocerium takes on the opposite role to the traditional system; instead of a natural flint rock striking tiny iron particles from a firesteel, a striker (which may be in the form of hardened steel wheel) strikes particles of ...
Its most common use is in the pyrophoric ferrocerium "flint" ignition device of many lighters and torches. Because an alloy of only rare-earth elements would be too soft to give good sparks, it is blended with iron oxide and magnesium oxide to form a harder material known as ferrocerium.
A spinning steel wheel provided a good stream of sparks when it engaged the flint, and a tinderbox designed to do this was known as a mill. [10] In a modern lighter or firesteel, iron is mixed with cerium and other rare earths to form the alloy ferrocerium. This readily produces sparks when scraped and burns hotter than steel would.
Fire making, fire lighting or fire craft is the process of artificially starting a fire. It requires completing the fire triangle , usually by heating tinder above its autoignition temperature . Fire is an essential tool for human survival and the use of fire was important in early human cultural history since the Lower Paleolithic .
