Ferrite magnet is a permanent magnet mainly made of SrO or BaO and Fe2O3 as raw materials. Compared with other permanent magnet, ferrite magnet is hard and brittle, and the magnetic energy is low. However, it is not easy to demagnetize is not easy to corrode, the production process is simple and the price is low, therefore, the ferrite magnet has the highest output in the entire magnet industry and is widely used in industrial production.
Ferrite is made of SrO or BaO and Fe₂O₃ as the main raw materials, and is sintered by ceramic technology. It is widely used in speakers, clicks, electric vehicles and other industrial fields.
