Brief introduction:

Ferrites (Ferrites) are non-metallic magnetic materials, also known as iron oxygens. It's made up of two oxides
Iron and one or more other metal oxides (e.g., nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide)
Made by preparation and sintering. Its relative permeability can be up to several thousand, its resistivity is 1011 times that of metal, small eddy current loss, suitable
To manufacture high frequency electromagnetic devices. Ferrite has five kinds: hard magnetism, soft magnetism, moment magnetism, spin magnetism and pressure magnetism. An iron magnet or iron
The product process and appearance are similar to ceramics, so it is also called magnetic porcelain. Ferrite is iron and one or more other suitable
Compound oxides of metal elements. Properties of semiconductors, usually used as magnetic media, ferrite magnetic materials with metal or
The most important difference between alloy magnetic materials is their electrical conductivity. Usually the resistivity of the former as Ω 102 ~ 108 cm, while the latter only
There are 10-6 ~ 10-4 Ω · cm.
