Hematite Fe2O3 PubChem

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the

Hematite Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread 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 which it forms a complete solid solution at temperatures above 950 °C

question about the charge of iron in Fe2O3? Yahoo Answers

Jan 27, 2008 I know that the charge of the Fe cation is 3+, but is this the correct way so find the charge of Fe? O's charge is always 2- & 2- "times" (O)3 = -6 because the charge of an ionic compound is neutral, Fe's charge must be 3+ because 3+ "times" (Fe)2 = 6 O= 6- Fe= 6+ the name of the ionic compound is iron(III) oxide This may sound like a dumb question, but I'm a moron when it comes to
