Rare earth free permanent magnet of sintered ferrite and procedure thereof
The embodiments of the present disclosure provide a rare-earth free sintered ferrite magnet. The sintered ferrite magnet provided in the present disclosure have the chemical formula Sro.9. Bao.iCaxAlyCozFei2-y-Oi9. The optimized quaontofa of Ca, Al and Co wre substituted in pure Sro.9Bao.1Fe12O9 to enhance the performance of ferrite magnet. A synthesis method to prepare Sro.9.xBao.iCaxAlyCozFe12-y-zOi9 hexaferrite magnet in bulk form is provided. The sintered ferrite magnet exhibit a substantial maximum energy product of 12.73 MGOe.
