Introduction: Ferrite ferrite is a non-metallic magnetic material, also known as ferrite. It is prepared by sintering of ferric oxide and one or more other metal oxides (eg, nickel oxide, zinc oxide, manganese oxide, magnesium oxide, yttrium oxide, yttrium oxide, etc.). Its relative permeability can be as high as several thousand, its resistivity is 1011 times that of metal, and its eddy current loss is small, which is suitable for making high-frequency electromagnetic devices. Ferrite has five categories: hard magnetic, soft magnetic, moment magnetic, gyromagnetic and pressure magnetic. The old name is iron oxide, magnetic material or iron oxide. Its production process and appearance are similar to those of ceramics. Therefore, it is also called magnetic porcelain. Ferrites are complex oxides of iron and one or more other suitable metal elements. The properties belong to semiconductors, which are usually used as magnetic media. The most important difference between ferrite magnetic materials and metal or alloy magnetic materials is electrical conductivity.
