hematite iron magnetite

Role of hydrazine/reducing agent to develop the magnetite ...

While, both magnetite (Fe3O4) & hematite (Fe2O3) are iron oxides, the oxidation state of iron (Fe) is not the same for both oxides. Hematite contains only the 3+ type of Fe. Magnetite in contrast contains both 2+ and 3+ Fe.
