Block Ceramic Magnets for Sale include barium ferrite (BaFe12O19), strontium ferrite (SrFe12O19) and it has high resistivity, big coercive force, can be effectively applied in the air gap magnetic circuit, especially suitable for small generator and permanent magnet motors. Permanent magnetic ferrite do not contain precious metals such as nickel, cobalt, has rich source of raw materials, simple process, low cost, can replace aluminum nickel and cobalt permanent magnet in system of magnetic separator, magnetic bearing, speakers, microwave devices, etc. But the maximum magnetic energy is low, temperature stability is low, quality of a material is brittle, fragile, low resistance to impact and vibration, unfavorable for measuring instrument and precision requirements of the magnetic device.
The ceramic magnets can be made in various shapes of circular, cylinder, square, tile-type.
The characteristic of ceramic magnets:
1. Processed by powder metallurgy method, low remanence and reversibility.
2. High coercive force, hard to be demagnetized, suitable for dynamic application.
3. Hard and crisp ,usually cut by diamond tools.
4. Main composed of oxide, not easy to be eroded.
5. Usually work at - 40 °C to + 200 °C
6. Both isotropic and anisotropic magnets are available. The magnetic properties of isotropic ferrite are low. Since they have nearly the same magnetic properties in all directions, so isotropic ferrite magnets can be magnetized in many different directions or in multi-poles. Anisotropic ferrite magnets have better magnetic properties compare with isotropic ferrite magnets. However this type of magnets can only be magnetized along a preferred direction.
Application of ceramic magnets
1. Widely used in permanent magnetic electric machinery, speakers,etc.
2. Also used in all kinds parts of apparatus like micro electric machinery, electro-acoustic device, copying machines, medical equipment, etc.
