Pyrophoric scale can be found on metal surfaces where they have reacted with oxygen or moisture in the air, leading to the formation of a flaky, easily-ignited layer. This scale is commonly seen on materials like iron, steel, and certain alloys exposed to high temperatures or in corrosive environments. It typically appears as a reddish-brown or black brittle layer that can ignite spontaneously when exposed to air.
A pyrophoric substance (from Greek purophoros, "fire-bearing") will ignite spontaneously.
Fine powders of hafnium are pyrophoric.
Neptunium as a powder is pyrophoric.
Plutonium is pyrophoric as a fine powder.
self heating or pyrophoric materials
A material that will spontaneously ignite and burn when exposed to air is called pyrophoric. Pyrophoric materials are highly reactive and can pose fire hazards if not handled properly.
self-heating or pyrophoric materials
Any special precautions; but hafnium as a a fine powder can be pyrophoric.
Uranium in powdered form is very pyrophoric.
Uranium is easily oxidized by oxygen.In powdered form is pyrophoric.
Usually this requires isolating the susbtance from the atmosphere. This usually entails keeping the substance under an under atmosphere, such as in a sealed container of argon. White phosphorus, unlike many other pyrophoric substances, may be stored underwater.
