Hard Ferrite magnets are commonly known as Ceramic magnets due to the process used to producethem.Ferrite magnets are manufactured mainly of strontium or barium ferrites and iron oxide.Hard Ferrite(Ceramic) magnets are produced as lsotropic and Anisotropic types. Isotropic type magnets are produced without orientation and can be magnetized in any direction.On the other hand, Anisotropic magnets are exposed to an electromagnetic field during their process to achieve higher magnetic energy and properties. This is done by pressing dry powders or slurry into a desired die cavity with or without orientation. After the compaction into the dies the parts are exposed to a high temperature, a process known as sintering.Sintered Arc Segment Tile Ferrite Permanent Magnets
Ferrite magnets main qualities:
High coercivity(=high resistance of the manet to demagnetization).
Highly stability under difficult environment conditions with no need for a coating to protect the magnet.
High resistance to oxidation.
Durability-the magnet is stable and constant.
Ferrite magnets popular uses:
Automotive industry, electric motors(Dcbrushless and others),magnetic separators (mainly plates),home appliances and more. Segment Ferrite Permanent Motor Rotor Magnets
