Fe2O3 can be obtained in various polymorphs. In the primary polymorph, α, iron adopts octahedral coordination geometry. That is, … See more

The most important reaction is its carbothermal reduction, which gives iron used in steel-making:
Fe2O3 + 3 CO → 2 … 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 … 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:
4 Fe + 3 O2 + 2 H2O → 4 FeO(OH)
The resulting … See more
