PHYSICAL PROPERTIES OF SINTERED FERRITE MAGNETS

 

 
What's the feature of ceramic strontium ferrite magnet made by wet compression molding?
 

• Composition - Contain strontium ferrite (SrFe12O19) as the primary magnetic material. Strontium ferrite has good magnetic properties and is inexpensive to produce.
• Density - Have a high relative density of around 95% or more after sintering. This gives good mechanical strength.
• An-isotropy - Exhibit strong magnetocrystalline an-isotropy due to their hexagonal crystal structure. This results in a preferred direction of magnetization along one axis.
• Particle shape - The strontium ferrite powder used typically has a hexagonal platelet morphology which helps promote magnetic an-isotropy during molding and sintering.
• Molding method - The powder is mixed with a liquid binder and compression molded into a dense green compact using high pressures. This orients the an-isotropic particles.
• Firing process - The compact is then sintered at high temperature to develop density while preserving the induced magnetic anisotropy orientation from molding.
• Remanence - Have a maximum magnetic flux density or remanence along the axis of anisotropy, but little/no remanence perpendicular to it.
• Coercivity - Usually have medium to high coercivity depending on additives, density, and anisotropy level achieved.
