Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe2O3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as an important

Hematite | Fe2O3 - PubChem

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the ...
