Hematite | Fe2O3 - PubChem
Occurs naturally as the mineral hematite; produced synthetically by calcining iron salts such as ferrous sulfate, ferric alums, or organic iron salts under oxidizing conditions (the iron compound used and the reaction conditions determine the color of the pigments)Hematite - Wikipedia,Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice 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 this it forms a complete solid solution at temperatures above 950 °C (1,740 °F). Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is minedName The Iron Compound In Haematite,Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide Fe 2 O 3, that constitutes the most important iron ore because of its high iron content 70 percent and its abundance.
