General description

Iron (III) oxide (Fe2O3) is an inorganic compound. It is one of the three main types of iron oxide. The other two are the rare iron (II) oxide (FeO) and the naturally occurring iron (II, III) oxide (Fe3O4), found in the mineral magnetite. In the steel industry Fe2O3 is the primary source of iron. In addition to being ferromagnetic, Fe2O3 is easily attacked by acids.

Application

Iron (III) oxide is used:
  • As a catalyst in the reduction of nitroarenes.
  • As an oxidizing agent in the synthesis of [11C] Phosgene ([11C] COCl2).
