Abstract: The effect of grain orientation on the magnetic properties of anisotropic and sintered strontium ferrite was examined by scanning electron microscopy, transmission electron microscopy and magnetic measurement. The results showed that the needle-like particles of ferrite with arranging along C axis in good order were found in the strontium ferrite powder, originating from the crushed and milled waste magnet, which did not have bad effect on the quality of products. The particles in sintered permanent magnetic strontium ferrite presented hexagonal structure. The higher the orientation degree, the better the magnetic properties were. The strength of magnetic field and the addition of binder had significant effect on the orientation degree and magnetic properties of permanent magnetic strontium ferrite.
