Ferrite magnets, made by molding powder mixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also called ceramic 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 controlled furnace what is heated with electricity or coal. Though hard ferrite magnet is with low magnetic property, it is still a preferable choice to engineer in their design due to several factors: abundantly available raw material,the cheapest cost among permanent magnet family, low density, excellent stability of chemistry, high maximum working temperature and Curie temperature.

Features
1. Ferrite or ceramic magnets are still the most widely used magnets with a maximum energy product of 1 to ± 4.3 MGOe.
2. Due to the environmental requirements which are becoming more stringent barium ferrite has been replaced by strontium ferrite during the last years.
3. Ferrite is the cheapest magnetic material and has a high corrosion resistance making coating unnecessary.
4. This magnetic material is hard and fragile and must be processed with diamond, preferably when it is not in a magnetic state.
