Characteristics for flat ceramic magnets:
* Low cost, high-energy, good electric insulation and excellent resistance to demagnetization.
* High coercive force, high electric resistance, long-time stability, and economical price.

Type for flat ceramic magnets:
Isotropic ferrite magnets
Anisotropic ferrite magnets

Manufacturing Process for flat ceramic magnets:
1. Dry process:
By dry process, can produce isotropic & anisotropic magnets. The tool can be changed and developed easily.
2. Wet process:
By wet process, only anisotropic magnets can be produced. It is complicated to change the tool and the tooling charge is much higher.

Magnetization for flat ceramic magnets:
1. Isotropic ferrite magnets are not oriented and can be magnetized in any direction;

2. Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
