Ferrite or Ceramic Magnet,made by molding powdermixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also calledceramic magnet.
Along with deepening of research, some additives such as cobalt(Co) and lanthanum (La) are mixed together to improve the magnetic performance.
The molded powder metallic green is sintered inside a temperature controlledfurnace what is heated with electricity or coal. Though hard ferrite magnet iswith low magnetic property, it is still a preferable choice to engineer in theirdesign due to several factors: abundantly available raw material,the cheapestcost among permanent magnet family, low density, excellent stability ofchemistry, high maximum working temperature and Curie temperature.
