Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main … See more Fe2O3 can be obtained in various polymorphs. In the main one, α, iron adopts octahedral coordination geometry. That is, each Fe center is bound to six oxygen ligands. In the γ polymorph, some of the Fe sit on … See more The most important reaction is its carbothermal reduction, which gives iron used in steel-making: Fe2O3 + 3 CO → 2 Fe + 3 CO2 Another redox reaction is the extremely exothermic thermite reaction with aluminium See more Iron industry The overwhelming application of iron(III) oxide is as the feedstock of the steel and iron industries, e.g. the production of iron, steel, and many alloys. See more • NIOSH Pocket Guide to Chemical Hazards See more Several hydrates of Iron(III) oxide exist. When alkali is added to solutions of soluble Fe(III) salts, a red-brown gelatinous precipitate forms. This is not Fe(OH)3, but Fe2O3·H2O (also written as Fe(O)OH). Several forms of the hydrated oxide of Fe(III) exist … See more Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: See more • Chalcanthum See more WebWith limited dissolved oxygen, iron (II)-containing materials are favoured, including FeO and black lodestone or magnetite (Fe 3 O 4 ). High oxygen concentrations favour ferric materials with the nominal formulae Fe (OH) 3−x O x⁄2. The nature of rust changes with time, reflecting the slow rates of the reactions of solids. [5]
