Product Description
Ferrite (ceramic) magnets are essentially composed of oxide materials with barium carbonate or strontium carbonate, manufactured under a powder metallurgical process
The feature of low recoil permeability, along with the high coercive force, makes them highly resistant to demagnetizing fields.
Ferrite magnets have good anti-corrosion performance, no surface treatment needed.
Ferrite Magnet
The feature of low recoil permeability, along with the high coercive force, makes them highly resistant to demagnetizing fields.
In addition, their relatively low specific density and economical cost are also very attractive to the magnet designers. When designing the ferrite magnets for a particular application, primary consideration should be given to its shape limitation due to the powder metallurgical manufacturing process and the temperature dependence of ferrite materials.
Ferrite magnets have good anti-corrosion performance, no surface treatment needed.
There are two manufacturing process for ferrite magnets: dry process and wet process. By dry process, can produce isotropic & anisotropic magnets; by wet process, only anisotropic magnets can be produced.
Isotropic ferrite magnets are not oriented and can be magnetized in any direction; anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
For dry process, the tool can be changed and developed easily, while for wet process, it is complicated to change the tool and the tooling charge is much higher. At present, we have put our emphasis on arc segment magnets for electric motors, disc magnets and block magnets for special applications

Ferrite or Ceramic Magnet,made by molding powdermixture of about 80% Fe2O3 and about 20% either BaCo3 or SrO3, is also calledceramic magnet.
Along with deepening of research, some additives such as cobalt(Co) and lanthanum (La) are mixed together to improve the magnetic performance.
The molded powder metallic green is sintered inside a temperature controlledfurnace what is heated with electricity or coal. Though hard ferrite magnet iswith low magnetic property, it is still a preferable choice to engineer in theirdesign due to several factors: abundantly available raw material,the cheapestcost among permanent magnet family, low density, excellent stability ofchemistry, high maximum working temperature and Curie temperature.
