  • Ferrite | iron oxide compound | Britannica

    A ferrite is formed by the reaction of ferric oxide (iron oxide or rust) with any of a number of other metals, including magnesium, aluminum, barium, manganese, copper, nickel, cobalt, or even iron itself. A ferrite is usually described by the formula M(Fe x O y), where M represents any metal that forms divalent bonds, such as any of the elements mentioned earlier.
