| 简介 |
A method is provided for producing an artificial permanent magnet, in a powder preparation step a main phase powder, which includes a rare-earth transition metal compound with permanently magnetic properties and has a first average particle size, is prepared and an anisotropic powder, which has a higher anisotropy field strength than the main phase powder and has a second average particle size, is prepared, wherein the second average particle size is smaller than the first average particle size. In a subsequent powder mixing step, the main phase powder and the anisotropic powder are mixed together to form a powder mixture and, in a subsequent heat treatment step, this powder mixture with the main phase powder of the first average particle size and with the anisotropic powder of the second average particle size is sintered to form an artificial permanent magnet. |
