What is permanent magnet ferrite?

Permanent magnet ferrite is a kind of magnetic ceramic material, composed of iron oxides and rare earth elements. It has a high magnetization and coercivity, so it is widely used in the manufacture of various permanent magnet devices, such as magnets, motors and sensors. Permanent magnet ferrite has good corrosion resistance and high temperature resistance, so it has been widely used in industrial and scientific fields.

Permanent magnet ferrite is a type of magnet that is made from a material called ferrite, which is a type of ceramic compound composed of iron oxide (Fe2O3) combined with other metallic elements such as barium, strontium, or lead. This combination of materials creates a magnetic material with strong permanent magnetism. Permanent magnet ferrite is commonly used in various applications such as electric motors, speakers, and magnetic assemblies.

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.
