Hematite Physical Optical Properties, Occurrence, Uses

Hematite is dense and hard, it is the most important ore of iron because of its high iron content and its abundance. The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses. It also occurs as

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a complete solid solution at temperatures above
