The permanent ferrite
The permanent ferrite has been produced since 1950s. It is a ferromagnetic metallic oxide which is produced by powder metallurgy. It is divided into Ba and Sr. It can be molded into isotropic and anisotropic magnets its necessity of magnetic force. The permanent ferrite is hard to be demagnetized and anticorrosion, and the working temperature reaches 250 degrees Celsius, the Curie temperature reaches 450degrees Celsius. It is a material which is hard but fragile and can be cut and processed by diamond grinding wheels or other molds. This kind of product is wildly used in magnetoelectric motors, sports equipments, medical equipments, aquatic equipments, loudspeakers and so on.
