Ceramic
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. |
