fer⋅rite

[fer-ahyt]
–noun
1. Chemistry. a compound, as NaFeO2, formed when ferric oxide is combined with a more basic metallic oxide.
2. Metallurgy. the pure iron constituent of ferrous metals, as distinguished from the iron carbides.

Origin:
1875–80; < L ferr(um) iron + -ite 1
fer·rite   (fěr'īt')   
n.  
  1. 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. Also called ferrate.
  2. Iron that has not combined with carbon, occurring commonly in steel, cast iron, and pig iron below 910°C.

ferrite

a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally gray or black and are polycrystalline-i.e., made up of a large number of small crystals. They are composed of iron oxide and one or more other metals in chemical combination.
