WebFerrite, also known as -ferrite (-Fe) or alpha iron, is a materials science term for pure iron, with a body-centered cubic B.C.C crystal structure. It is this crystalline structure which gives steel and cast iron their magnetic properties, and … Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity. Many ferrites adopt the spinel structure with the formula AB2O4, where A and B represent various metal cations, usually including iron (Fe). Spinel ferrites usu…
WebFerrite is a substance represented by the chemical formula MFe2O4 or MO·Fe2O3 (M is not a specific element symbol, but an abbreviation for various metal elements), which is a compound of an oxide of a divalent metal ion (M2+) and an oxide of a trivalent iron ion (Fe3+).
