Oxidation state of oxygen in F eO and F e2O3 is -2. Let the oxidation state of Fe in F eO and F e2O3 be x and y respectively. As we know that the sum of the oxidation states of all the atoms or ions in a neutral compound is zero. Hence the oxidation number of F e in F e3O4 are +2 and +3 respectively.
Reduction of Iron Oxides with Hydrogen—A Review
In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, Fe.If the reduction temperature is lower than 570 °C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to Fe.The intermediate oxide, wüstite Fe (1−x) O, is not stable at temperatures lower than 570 °C. At reduction temperatures …
