| 简介 |
Provided are a rare-earth permanent magnet and a method for manufacturing a rare-earth permanent magnet with which the magnetic characteristics of the permanent magnet are improved and manufacturing efficiency is significantly enhanced. A magnet raw material is pulverized into a magnet powder, and a compound (12) is produced by mixing the pulverized magnet powder and a binder. Then, by hot-melt forming the produced compound (12), a green sheet (14) formed into a sheet is prepared on a support base material (13). Then, the formed green sheet (14) is heated and softened, and in a state where a plurality of said heated green sheets (14) have been laminated, magnetic field orientation is performed by applying a magnetic field thereto. Further, the magnetic-field-oriented green sheets (14) are sintered. In this way, a permanent magnet (1) is manufactured. |
