Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding.
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.
What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?
Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.
High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.
Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.
Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.
Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.
Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.
