Calcium Lanthanum Permanent Magnetic Ferrite Coupled with Soft Magnetic Ferrite
This paper introduces the production method of calcium lanthanum permanent magnetic ferrite coupled with soft magnetic ferrite components. This type of calcium lanthanum permanent magnetic ferrite has excellent magnetic properties. Soft magnetic ferrite components (CoFe2O4) can be coupled effectively with permanent magnetic ferrite (the main ingredients: Ca0.548Sr0.120La0.542Fe12O19) by adding the additives (SrB2Si0.67O5.34 and CaSiO3), which can promote the sintering of the liquid permanent magnetic ferrite. This calcium lanthanum permanent magnetic ferrite can be significantly improved in the microstructure, density, magnetic properties.
