| 简介 |
A process for magnet production by which a magnet not only having sufficient values of Br and HcJ but having a sufficiently high squareness ratio can be obtained. The process for magnet production is characterized by comprising a first step in which a heavy rare-earth compound containing a heavy rare-earth element is adhered to a sinter of a rare-earth magnet and a second step in which the sinter having the heavy rare-earth compound adherent thereto is heat-treated, the heavy rare-earth compound being the hydride of a heavy rare-earth element. |
