抄録

The magnetic product produced by the conventional magnetically aligning press is restricted in its shape and size. To solve this problem, this paper presents a novel process, in which the pressing process is separated from the aligning one. As an example, strontium ferrite powder mixed with an MIM binder was compacted in a die, followed by alignment under a magnetic field. After then, effects of forming conditions on the magnetic properties of the compacts, for example, the degree of orientation, B_r/J_s, were examined. The maximum value of B_r/J_s reached 0.950, indicating that the well oriented magnetic compact could be obtained by this procedure.<BR>The MIM binder is preferable to have a low viscocity for a high orientated compact and a good compactibility, a good shape stability as well as an easiness in mold release for the compact production. Moreover, simultaneous addition of zinc stearate with the MIM binder to the compact was found to improve the above behaviors of the binder for the compact.
