Ceramic Magnets

ceramic magnetceramic magnet 2

Ferrite magnets are composed essentially of oxide materials manufactured under a powder metallurgical process. Their magnetic properties feature a relatively low residual flux density, coupled with a high coercive force.

The feature of a low recoil permeability, along with the high coercive force, makes them highly resistant to demagnetizing fields. In addition, their relatively low specific density and economical cost are also very attractive to the magnet designers. When designing the ferrite magnets for a particular application, primary consideration should be given to its shape limitation due to the powder metallurgical manufacturing process and to the temperature dependence of ferrite materials.

Since the magnetic characteristics of ferrite magnets are relatively sensitive to changes in temperature, adequate consideration should be made regarding the application purpose.
