Description

Gray metallic, pyrophoric powder; [CAMEO]

Sources/Uses

Iron powder is used in metallurgy and as a catalyst in manufacturing; [CAMEO] Used to treat anemia and as a dietary supplement in pregnancy; [Olson, p. 277] Iron nanoparticles include the fine needles used in magnetic recordings; Magnetic iron oxide nanoparticles have biomedical applications including targeted drug delivery and MRI imaging (Feridex); [HSDB]

Comments

Fine iron powder can ignite spontaneously. Reacting with moisture in the air, it produces flammable hydrogen gas. [CHEMINFO] Occupational asthma in 3 welders confirmed by bronchoprovocation testing; [Malo] See "Iron salts, soluble" and "Iron oxide."
