Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun Any of a group of nonmetallic, ceramiclike, usually ferromagnetic compounds of ferric oxide with other oxides, especially such a compound characterized by extremely high electrical resistivity and used in computer memory elements, permanent magnets, and various solid-state devices.
- noun Iron that has not combined with carbon, occurring commonly in steel, cast iron, and pig iron below 910°C.
from The Century Dictionary.
- noun 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.
- noun 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).
- noun Pure iron as separated out (from iron carbides) in the cooling of steel.

The engineers are running programs that show how adding tiny amounts of alloys to ferrite and martensite—crystalline structures of iron—during the steelmaking process changes the steel's strength, as well as its ability to be shaped into different parts.

Even if ‘doing it on his own’ involved nothing more strenuous than taking prepackaged parts from Radio Shack and soldering them together (seriously, have you even tried to wind your own ferrite variable coil?).
