Sintered Ferrite / Ceramic Magnets

Magnetic material and assemblies - Sintered FerriteDeveloped in the late 1950’s, sintered ferrite (ceramic magnets) are manufactured from a composite powder containing 80% iron oxide and 20% barium or strontium oxide. This powder is die pressed into a component that is sintered in a kiln at approximately 1200°C.

Sintered ferrite has a wide range of applications due to their low cost. They can be made in arcs, blocks, rings, discs and other shapes. Principal applications are DC motors, loudspeakers, reed switch operations, magnetic separator assemblies and general holding devices. Sintered ferrite has a good resistance to demagnetization and can be magnetized before or after assembly without danger of losing any performance. It can be used in operating temperatures ranging from ‐40°C to + 250°C.
