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.

Introduction Of Fan Motor:
Rotor Magnet: Permanent magnet ferrites are used as magnets in the rotor of fan motors. The rotor is the rotating part of the motor that is connected to the fan blades. Ferrite magnets provide a strong and stable magnetic field when an electric current passes through the stator coils, creating a force that causes the rotor to rotate.
Motor Efficiency: Permanent magnet ferrites contribute to the efficiency of fan motors. They offer high magnetic properties, such as a high coercivity and strong magnetic field, which allow for efficient energy conversion from electrical to mechanical energy. This results in improved motor performance and energy efficiency.
