Ceramic, also known as ferrite, magnets are made of a composite of iron oxide and barium carbonate (BaCo3) or strontium carbonate (SrCO3).


Widely available since the 1950's, this material is commonly available and at a lower cost than other types of materials used in permanet magnets.Ceramic magnets are made using pressing and sintering. Sintered magents are a type of ceramic composed of the compressed powder of the alloy material being used.Sintering involves the compaction of fine alloy powder in a die and then fusing the powder into a solid material with heat. While the sintered magets are solid ,their physical properties are more similar to a seramic and are easily broken and chipped.Ceramic magents are brittle and hard generally requiriing diamond wheels to grind and shape.These magnets come in a number of different grades. Ceramic-1 is an isotropic grade with equal magnetic properties in all directions.

Ceramic grades 5 and 8 are anisotropic grades. Ansotropic magents are magnetized in the direction of pressing.The anisotropic method delivers the highest energy product among ceramic magnets at values up to 3.5 MGOe ( Mega Gauss Oersted). Ceramic magnets have a good balance of magnetic trength, resistance to demagnetizing and economy. They are the most wide used magents today.
