    • n ferrite a solid solution in which alpha iron is the solvent

Century Dictionary and Cyclopedia
    • n ferrite A term proposed by Vogelsang to include indeterminable mineral substances of a reddish color, frequently observed in certain igneous rocks when they are examined in thin sections under the microscope. They probably consist in most cases of hydrous oxid of iron.
    • n ferrite In chem.: A compound of ferric oxid (Fe2O3) with a more basic metallic oxid, as calcium ferrite (CaFe2O4), from the union of ferric oxid with lime (CaO). The mineral franklinite consists essentially of zinc ferrite, and magnetite or magnetic iron ore (Fe3O4) may be viewed as iron ferrite (FeO.Fe2O3).
    • n ferrite Pure iron as separated out (from iron carbides) in the cooling of steel.
