An experiment was carried out to investigate the effect of Ba Stearate as a reducing agent on the magnetic and physical properties of anisotropic type ferrite magnets. It was found that the magnetic properties of were improved by adding 0.3 wt% of Ba Stearate, 0.5 wt% of , and 0.5 wt% of CaO together. The optimum conditions for making magnets were as follows; semisintering condition: h in nitrogen gas atmosphere, drying condition: h in air, sintering condition: h in nitrogen gas atmosphere. Magnetic and physical properties of a typical sample were = 0.46 T, = 0.43 T, = 182.3 kA/m, = 177.2 kA/m, = 33.8 kJ/, = and = and = 1332 kA/m.
