Sintered ferrites (also known as ceramic magnets) were developed and produced in the 1950's;
Sintered ferrite magnets mainly include barium ferrite (BaO•6Fe2O3) and strontium ferrite (SrO•6Fe2O3); sintered ferrite is divided into isotropic magnets and anisotropic magnets.
Performance: The magnetic properties of isotropic sintered ferrite are weak, and have the same magnetic properties in any direction.
Multi-pole magnetization in any direction; Anisotropic sintered ferrite magnets have higher magnetic properties than isotropic ones,
It can only be magnetized in the orientation direction of the magnetic field during molding; the main raw material of sintered ferrite is oxide,
Therefore, it will not be corroded by high temperature, high humidity or chemical substances (except strong acid and alkali).
Application field: Because the raw materials are cheap and the production process is relatively simple, the cost is low,
Therefore, sintered ferrite is by far the most widely used permanent magnet material;
It is widely used in permanent magnet motors, DC motors, speakers, reed switches, magnetic separators and adsorption devices, etc.
Others: sintered ferrite has excellent demagnetization resistance, no magnetic flux loss before and after assembly and magnetization;
The working temperature of sintered ferrite is -40°C to +250°C, and the temperature coefficient is poor;
The temperature coefficient of Br is -0.2%/°C, that is, for every 1°C increase in temperature, Br decreases by 0.2%;
Sintered ferrite has high hardness and can be processed by wire cutting and grinding;
Sintered ferrite is brittle and fragile, so it should be handled with care during production and transportation.
