Iron ferrite (FeO·Fe2O3) is a type of magnetite that forms when iron rusts. It's one of the three primary phases of pure iron under ordinary temperatures and pressures.

Uses: Iron ferrite is primarily used in magnetic applications such as permanent magnets, transformers, and electric motors due to its strong magnetic properties.

Location: Iron ferrite is found naturally in various minerals like magnetite (Fe3O4) and hematite (Fe2O3).
