| 简介 |
There are provided a rare-earth permanent magnet and a manufacturing method of a rare-earth permanent magnet capable of improving magnetic properties with drastically enhanced manufacturing efficiency. In the method, magnet material is milled into magnet powder. Next, the magnet powder and a binder are mixed to obtain a mixture 12. Next, the thus prepared mixture 12 is formed into a long-sheet-like shape on a supporting base 13 by hot-melt molding so as to obtain a green sheet 14. The thus formed green sheet 14 is heated to soften and a magnetic field is applied to multiple layers of the heated green sheet 14 for magnetic field orientation. The green sheet 14 subjected to the magnetic field orientation is sintered and thereby a permanent magnet 1 is obtained. |
