| 摘要 |
The invention relates to a method for producing a permanent magnet (20), the method comprising the steps: (a) preparing a mixture (13) comprising a powder (10) of a magnetic material (12), and a binder composition (14) comprising at least one precursor compound for silicon oxide, and at least one precursor compound of a further oxide; (b) molding the mixture (13) into a green part (15) ; (c) thermally treating the green part (15) for transferring at least parts of the of the binder composition (14) into the oxide, and (d) successively to or simultaneously with step (c), sintering the green part (15) to form a glass-, ceramic-, or glass-ceramic matrix (21) from the oxides, which embeds the particles (11) of the magnetic material (12). The permanent magnet (20) that can be produced using the method comprises cores (15) of a permanent magnetic material (12) having an average particle diameter of 1 µm at the most, and a matrix (21) of a diamagnetic or paramagnetic material (22), in which the cores (15) are embedded. |
