| 简介 |
A method for preparing a sintered rare earth-based magnet using a melting point depression element and a sintered rare earth-based magnet prepared by the same are disclosed. The method for preparing a sintered rare earth-based magnet according to the present invention includes the steps of : heating an R—Fe—B based magnet powder to a predetermined temperature to produce a sintered magnet, in which R is a rare earth element or a combination of rare earth elements; coating the surface of the produced sintered magnet with a coating solution prepared by mixing a heavy rare earth powder and a melting point depression element powder in a solvent; and heat-treating the coated sintered magnet. |
