— The name hematite is derived from the Greek word for "blood aim at" because hematite can be red, as in rouge, a powdered form of hematite. Hematite is the mineral form of iron (III) oxide (Fe 2 O 3), one of several iron oxides. Hematite crystallizes in the rhombohedra system, and it has the same crystal structure as ilmenite and corundum.
