Hematite Fe2O3 (iron(III) oxide)

In this video, we explore hematite, an important iron ore with the chemical formula Fe2O3 (iron(III) oxide). Hematite can appear black to steel-gray or reddish-brown and is known for its red streak. It ranks 5.5 to 6.5 on the Mohs hardness scale and has no cleavage. Hematite can form massive structures or plate-like crystals, with a specific gravity between 4.9 and 5.3. Discover where hematite is found, including major deposits in Brazil, Australia, and the U.S., and learn about its use as a source of iron and pigment.
