A solid solution in which alpha iron is the solvent
Ferrite, also known as u03B1-ferrite (u03B1-Fe) or alpha iron, is a solid solution of limited amounts of carbon in 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 is the classic example of a ferromagnetic material.
Ferrites are chemical compounds, ceramic with iron(III) oxide Fe2O3 as their principal components . Many of them are magnetic materials and they are used to make permanent magnets, ferrite cores for transformers, and in various other applications.
The interstitial solid solution of carbon in body-centered cubic iron; any of a class of metal oxides which show ferrimagnetism; used in transformers, inductors, antennas, recording heads, microwave devices, motors and loudspeakers; The anion FeO2^2-, and any of the salts (formally derived from ...
