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.
