What Is Fe2O3?

The other main oxides of iron are FeO and Fe3O4 Fe2O3 is the most important iron ore because of its rich abundance; it is the main source of iron for the steel industry Hematite appears as a reddish-brown, magnetic solid that is insoluble in waterOct 19, Hematite topic Hematite , also spelled as haematite , is the mineral form of iron(III) oxide (FeO), one of several iron oxides Hematite crystallizes in the rhombohedral lattice system , and it has the same crystal structure as ilmenite and corundum.
