Seeing the future of magnets.
Ferrite magnets are compounds made primarily from iron oxide, with small amounts of barium and strontium added and then sintered. After sintering, the material is crushed into particles of about 1μm, molded, and sintered again to create ceramic products. In hard ferrites, permanent magnets are produced by magnetizing them with an electromagnet after sintering. They possess relatively strong magnetic properties while being inexpensive, making them suitable for various applications.

basic information
There are two types of production technology: wet and dry, but in China, production is predominantly done using wet technology. It is a permanent magnet that exhibits strong magnetic properties, known as hard magnetism, and is also referred to as ceramic magnets. They are classified into "isotropic ferrite" and "anisotropic ferrite" based on differences in coercivity. In anisotropic ferrite, the "easy magnetization direction" aligns with the internal crystal units due to pressure applied in a magnetic field during shaping. It has high permeability and is known as a ceramic magnet. The residual magnetic flux density (Br) is 0.4-0.45 Tesla, and the coercivity (Hcj) is 300 - 400 kA/m (3,700 - 5,000 Oersted).
