They are made from a combination of either Barium (BaO.6Fe2O3) or Strontium Ferrite (BaO.6Fe2O3) and Iron Oxide1 and exhibit a high degree of coercive strength, making them more resistant to demagnetization. Ceramic Magnets are a low cost solution to an endless list of magnetic applications. Hard Ferrite or Ceramic magnets can be produced with either isotropic or anisotropic properties. Anisotropic properties are derived from the high magneto-crystalline shape anisotropy of the ferrite particles. Physical orientation of the ferrite particles is necessary in the pressing process to achieve magnetic alignment. Hard Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -400C and +2500C. As temperature increases, remanence decreases by O.2%/0C whereas coercivity increases by O.3%/0C. At very low temperatures there is a risk of permanent demagnetization in magnet systems with low working points.
