Hematite - Wikipedia

Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known iron oxide mineral and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and...

Hematite – Virtual Museum of Molecules and Minerals

Hematite. Mineral Description. Hematite is an iron-oxide mineral of the Oxides and Hydroxides group, with structural formula [alpha-Fe2O3]. The structure is similar to that of corundum, and consists essentially of a dense arrangement of Fe3+ ions in octahedral coordination with oxygen atoms in hexagonal closest-packing.
