Ceramic Magnets offer the best value when comparing cost with other type of magnets. Ceramic (Ferrite) magnets are inexpensive, moderate in magnetic strength, and they are easily magnetized in a variety of formats. Ceramic magnets offer good corrosion resistance and generally do not require a coating or plating. Consideration should be given to the grade of alloy when exposing Ceramic magnets to temperature extremes. Ceramic (Ferrite) magnets have good resistance to external demagnetization fields because of its high Intrinsic Coercive Force (Hci) . This resistance and low cost makes Ceramic magnets a popular choice for electromechanical applications.
Ceramic (Ferrite) magnets are very hard and brittle. Like all magnetic materials, ceramic should not be used as a structural element in a design. Ceramic (Ferrite) magnets are particularly prone to cracking when the application involves impacts or flexing. As with most ceramic, the ferrite magnets should not be exposed to heating or cooling rates greater than 200°F per hour.

Ceramic Magnets Manufacturing Process

Ceramic (Ferrite) Magnets are produced by calcining a mixture of iron oxide and strontium carbonate to form a metallic oxide. A multiple stage milling operation reduces the calcined material to a small particle size. The powder is then compacted in a die by one of two methods. In the first method, the powder is compacted dry which develops an isotropic magnet with weaker magnetic properties, but with better dimensional tolerances. Often times a dry pressed magnet does not require finish grinding. In the second method, the powder is mixed with water to form slurry. The slurry is compacted in a die in the presence of a magnetic field. The applied field creates an anisotropic magnet which exhibits superior magnetic properties, but usually requires finish grinding.

The compacted parts which approximate the finished geometry are then sintered at high temperatures to achieve the final fusion of the individual particles. Final shaping is achieved by diamond abrasives. Usually the pole faces of the ceramic (ferrite) magnets will be ground and the remaining surfaces will exhibit "as sintered" tolerances and physical characteristics
