Ceramic magnets are also referred to as ferrite magnets. They were first developed in the 1960’s as a low cost alternative to rare earth magnets. Ceramic magnets are made of strontium carbonate and iron oxide which may give them their charcoal gray appearance. Ceramic magnets are mostly available in the form of rings, disc, cylinders, blocks and sometimes arcs for motors. Ceramic material is less expensive than alnico and rare earth magnets. They are difficult to mould thus available in basic shapes. Ceramic magnets feature a low service temperature when compared to alnico but is greater than rare earth. Grade 8 is the strongest ceramic material in the market today. The application for ceramic magnets extends to DC brushless motors, MRI, speaker magnets, DC permanent magnet motors used mostly in cars, separator and magnetic assemblies.
