General Description for Ferrite Magnets
Magnetic materials are fundamental functional materials of electronic industry. As important parts of magnetic materials, hard ferrite materials play a heavy role in electronic industry, electronic information industry, car industry, motorcycle industry etc. meanwhile, they are also widely used in medical treatment, mining and metallurgy, industrial automation, oil energy industry and civil industry.
Category of Ferrite Magnet:
- Temporary/soft magnet: Fe2O3, MnCO3, MgO, NiO, ZnO, etc.
- Permanent/hard magnet: BaFe12O19, SrFe12O9, etc.
Soft ferrites introduction
Soft ferrites are such magnetic materials which have been produced in a large scale and widely used for half a century. Due to their advantages such as high resistivity, low eddy current loss, high application frequency and rather low cost and capability of power transformation, impedance conversion and filtering, soft ferrites are used in nearly all the modern electronic devices and equipment.
