Fabrication method of rare earth permanent magnet with excellent magnetic property |
| abstract |
A method of manufacturing a rare-earth permanent magnet having excellent magnetic characteristics according to an embodiment of the present invention relates to a method of manufacturing an R-T-B type rare earth permanent magnet, comprising: preparing a permanent magnet parent alloy by melting an R-T-B type alloy; Crushing the permanent magnet parent alloy to prepare a permanent magnet powder; Forming a permanent magnet compact by applying a magnetic field to the permanent magnet powder in an inert atmosphere; Sintering the permanent magnet compact in a vacuum atmosphere to produce a sintered magnet compact having an oxygen content of 0.1 wt% or less; And a diffusion step of diffusing Dy and Tb into the sintered magnet formed body to produce a rare earth permanent magnet. |
