  Fe2O3 vs. Fe3O4 — What’s the Difference?

  20231212 · Fe2O3 is known as iron (III) oxide or hematite and has two iron atoms bonded to three oxygen atoms. On the other hand, Fe3O4 is called magnetite or iron (II,III) oxide and contains both ferrous (Fe2+) and ferric (Fe3+) iron ions with four oxygen atoms. In terms of magnetic properties, Fe2O3 is weakly magnetic. In contrast, Fe3O4, because of …
