As the request of clients
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 permanent 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 magnets are solid ,their physical properties are more similar to a ceramic and are easily broken and chipped.
Beneficial characteristics of ceramic magnets include their low cost, high coercive force, resistance to corrosion, and high heat tolerance. Drawbacks include their low energy product or “strengh”, low mechanical strengh, and the ferrite poweder on the surface of the material which can rub of and cause soiling.
