    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 latt 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 the main o
