Barium ferrite - Wikipedia

Barium ferrite is a common material for speaker magnets. The materials can be formed into almost any shape and size using a process called sintering, whereby powdered barium ferrite is pressed into a mold, and then heated until it fuses together. The barium ferrite turns into a solid block while still retaining its magnetic properties.

Material Characterization of Strontium Ferrite Powders for ...

For this study, different strontium ferrite powders were mixed with a filling ratio of about 60 vol% in a binder system and formed into green compacts. During the process of injection molding, a magnetic field was generated in the tool via a magnetic coil, which enables magnetization and orientation of the ceramic particles. All powders were successfully processed by MagnetPIM.

Permanent Magnets-Ferrite

Ferrite magnets are more commonly referred to as ceramic magnets. They are mostly composed of strontium and Iron oxide (SrO . 6Fe2O3) and offer solid performance with their low cost, higher coercive force than alnico and low recoil permeability. They are widely used for loudspeakers, small motors, generators, and rotors.

Ceramic Magnets | Ferrite | Permanent | AMF Magnets

Ceramic Magnets (also called Ferrite magnets) are made from a composite of iron oxide and barium carbonate or strontium carbonate which is sintered by compacting the fine alloy powder in a die and then fusing it with heat into solid material.Due to their high coercive force they are classified as hard materials (or hard ferrites), as are other permanent magnets including Neodymium, Samarium ...

Ferrite (magnet) - Wikipedia

A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc. They are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet.
