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 Cobalt and Alnico. Ferrite magnets can be used in temperatures up to 300 degrees Celsius. They are the most common permanent magnets in use today. Customized Radial Multipole Ferrite Rotor Magnets
The corrosion resistance of Ceramic/Ferrite is considered excellent, and no surface treatments are required. Ferrite magnets may have a thin film of fine magnet powder on the surface and for clean, non-contaminated applications some form of coating may be required. They are rather porous, and there may be applications where the surface should be sealed. Urethanes and epoxies work well. In addition, ferrite magnets lend themselves to printing.
Hard Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -40°C and +250°C. At extremely low temperatures there is a risk of permanent demagnetization in magnet systems with low permeance coefficients. Ferrite magnets have good intrinsic coercivity, making them resistant to demagnetizing effects. Hall Sensor Ferrite Radial 6-pole Magnetization Magnetic Ring
Ceramic ring magnets, also known as Ferrite Ring Magnets, come in a wide range of sizes. They are often used in loudspeakers and in resonance imaging and torque drives. Other applications for this permanent magnet include holding, door closures, joinery, and light fixtures. Ceramic Rings are similar to Ceramic Discs but with a hole in the middle, which makes them a versatile magnet option. One popular application is the fishing game, tied on a piece of string, or to pick up pins and needles. Ferrite magnets have less magnetic strength (due to the hole) but their inexpensive pricing makes them a customer favorite. 8 poles Radial Magnetization Magnetic Ring of Fume Pumping Machine, Outer Diameter 43mm Multipolar Ceramic Ring Magnet
