OverviewEtymology and historyMagnetismMine tailingsMarsJewelrySee alsoExternal links

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe2O3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form 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
