    Fe 3 O 4 is used as a catalyst in the Haber process and in the water gas shift reaction. The latter uses an HTS (high temperature shift catalyst) of iron oxide stabilised by chromium oxide. This iron chrome catalyst is reduced at reactor start up to generate Fe 3 O 4 from Fe 2 O 3 and Cr 2 O 3 to CrO 3.

    What Is the Difference Between Fe2+ and Fe3+? Reference

    Iron commonly exists in two primary oxidation states +2 and +3. When iron loses two electrons, it gains a +2 oxidation state and becomes the iron(II) ion, also known as ferrous ion. When iron loses three electrons, it gains a +3 oxidation state and becomes the iron (III) ion, also referred to as ferric ion.
