For the purpose of fabricating hard ferrite part with a complicated shape which has different alignment of the ferrite crystallites, the feasibility of two orientation forming methods were studied by using the compound of ferrite powder mixed with MIM binder. Combined sinter joining was at first carried out. Inner disk was compacted under magnetic field and ring compacted under non-magnetic field, respectively. In this case, a same MIM binder was used. The two compacts was assembled into a unit and then sintered at 1225℃ after debinder. As another orientation forming, a two-step integration forming method was tried. As the first step, inner disk was compacted under magnetic field using a high-melting point binder. As the second step, the compound mixed with a low-melting point binder was poured in the circumference of the inner disk compact under non-magnetic field and followed to integration. The joint strength of the ferrite part obtained by the two-step integration forming was superior to that of the joined compact by sinter joining.
