Beschreibung
Zusammenfassung:	A method of fabricating a modified ferrite magnetic powder and a method of fabricating a ferrite magnet are provided. The method of fabricating the modified ferrite magnetic powder includes steps of: providing a mixture; performing a calcination step to form a pre-processed object; performing a coarse pulverization step to form a plurality of coarsely-pulverized particles; performing a fine pulverization step to pulverize the coarsely-pulverized particles into first finely-pulverized particles and second finely-pulverized particles, respectively, wherein an average particle size of the first finely-pulverized particles is between 0.9 and 1 micron, and an average particle size of the second finely-pulverized particles is between 0.5 and 0.6 microns; and mixing the first finely-pulverized particles and the second finely-pulverized particles to obtain the modified ferrite magnetic powder, wherein an average particle size of the modified ferrite magnetic powder is between 0.7 and 0.8 microns.
