| 简介 |
There are provided a rare-earth permanent magnet, and a method for manufacturing a rare-earth permanent magnet and a system for manufacturing a rare-earth permanent magnet, capable of achieving improved shape uniformity. Magnet material is milled into magnet powder, and the milled magnet powder is formed into a formed body 40. The formed body 40 is calcined and then sintered using a spark plasma sintering apparatus 45, so that a permanent magnet 1 is manufactured. A die unit 46 included in the spark plasma sintering apparatus 45 that performs spark plasma sintering at least includes in one direction an inflow hole 50 configured to receive inflow of part of the pressurized formed body. |
