  1. ferroceriumnoun

    A pyrophoric alloy of iron and cerium that is used to make the flints for cigarette lighters


  1. Ferrocerium

    Ferrocerium (also known in Europe as Auermetall) is a synthetic pyrophoric alloy of mischmetal (cerium, lanthanum, neodymium, other trace lanthanides and some iron – about 95% lanthanides and 5% iron) hardened by blending in oxides of iron and/or magnesium. When struck with a harder material, the mixture produces hot sparks that can reach temperatures of 3,315 °C (6,000 °F) when rapidly oxidized by the process of striking the rod. Striking both scrapes fragments off, exposing them to the oxygen in the air, and easily ignites them by friction heat due to cerium's remarkably low ignition temperature of ~170 °C (338 °F). Its easy flammability gives ferrocerium many commercial applications, such as the ignition source for lighters, strikers for gas welding and cutting torches, deoxidization in metallurgy, and ferrocerium rods. Because of ferrocerium's ability to ignite in adverse conditions, rods of ferrocerium (also called ferro rods, spark rods, and flint-spark-lighters) are commonly used as an emergency fire lighting device in survival kits. The ferrocerium is referred to as a "flint" in this case despite being dissimilar to natural flint as both are used in conjunction for fire lighting, albeit with opposite mechanical operation.


  1. Ferrocerium

    Ferrocerium is a man-made metallic material that gives off a large number of hot sparks at temperatures at 3,000 °F when scraped against a rough surface, such as ridged steel. Because of this property it is used in many applications, such as clockwork toys, strikers for welding torches, so-called "flint-and-steel" or "flint spark lighter" fire-starters in emergency survival kits, and cigarette lighters, as the initial ignition source for the primary fuel. It is also commonly called ferro rod and most commonly of all, mistakenly, flint. As tinder-igniting campfire starter rods it is sold under such trade names as Blastmatch, Fire Steel, and Metal-Match for survivalists and bushcraft hobbyists. Some manufacturers and resellers mistakenly call them "magnesium" rods. It is also known in Europe as Auermetall after its inventor Baron Carl Auer von Welsbach.
