General Information
As important parts of magnetic materials, hard ferrite (ceramic) magnets play an important role in electrical, electronic information, car, motorcycle industries, etc. They are also widely used in medical treatment, mining and metallurgy, industrial automation, oil energy, and civil industries. Ceramic magnets are composed of iron oxide, barium and strontium elements. This class of magnets has a higher magnetic flux density, higher coercive force, and higher resistance to demagnetization and oxidation compared to other non-rare earth permanent magnets. The biggest advantage of such magnets is the low cost, which makes the hard ferrite magnets very popular in many permanent magnet applications. Due to their ceramic nature, ferrite magnets are very hard and brittle. Special machining techniques must be utilized for these magnets. Ceramic or hard ferrite magnets come in discs, cylinders, rings, blocks, and arcs and are charcoal grey.
