The raw material of the production of ferrite is iron oxide (FeZO3, FeO, FesO, etc.); MO (M:Ba, Sr, etc.) or its heating energy is easy to form the oxide M. The powder mixture was mixed with the powder material in an oxidizing atmosphere, so that the solid phase reaction was generated, and the MO - 6 FeZO3 magnetic phase was generated. The pre sintering material after crushing, by compression molding. If the magnetic field is formed in the form of an isotropic permanent magnet, the magnetic field can form an anisotropic permanent magnetic ferrite.
 

In order to make the particle orientation easier, the water is made into mud in the powder, which is wet, and no water is dry. After the pressure forming, the two sintering is to be made, and the finishing of the grinding machine is finished.
 

Oxidation of magnetite is mainly composed of Fe2O3 (iron oxide) BaCo3 (Anisotropic) or SrCo3 (strontium carbonate) metal powder forming, such a magnet has two types: one for Magnet Isotropic (Magnet), and the other for the same time, the same time, the same as the dry and wet. Features: magnetic uniform stability, permanent. Easy to be made into small size and same volume. Raw material (iron oxide) supply is adequate, the product price is low. Electrical resistance large, almost insulation
