摘要：
Among the permanent magnets hard ferrites, particularly M-type hexagonal ferrites (Sr-Ferrite and Ba-Ferrite) have special place by virtue of their low cost and reasonable magnetic properties. This paper gives a brief introduction of hard ferrites with special reference to strontium ferrite permanent magnet. Processing of, sintered and plastic - bonded magnet has been discussed. The effect of composition of strontium ferrite powders and that of various additives, such as CaO, SiO2, Al2O3, etc. on the magnetic properties have also been outlined.
