Sintered Ferrite Magnet (Hard Ferrite magnet, Ceramic Magnet) is made of ferric oxide/barium and strontium. It is included "Isotropic" and "Anisotropic" which is sintered through dry pressing or wet pressing by tool. It can be magnetized axially, radially, multi-poles axially and multi-poles on circumference, etc. As a low cost alternative to metallic magnets, Sintered Ferrite Magnet (Hard Ferrite Magnet, Ceramic Magnets) has won wide acceptance for high coercive force, excellent corrosion resistance, long-time stability and economical price. It has played an important role in electronic industry, car industry, medical treatment, mining and metallurgy industrial and etc, like motors, automotive sensors, loudspeaker, magnetic resonance imaging and etc. Besides, Sintered Ferrite magnet is widely use in Educational area.
