| 简介 |
Provided are a rare earth permanent magnetic powder, a bonded magnet and a device using the bonded magnet. The rare earth permanent magnetic powder comprises 4-12 at.% of Nd, 0.1-2 at.% of C, 10-25 at.% of N and 62.2-85.9 at.% of T, wherein T is Fe or FeCo, and the rare earth permanent magnet has a main phase of a hard magnetic phase having a TbCu7 structure. During the preparation, the rare earth permanent magnetic powder can effectively avoid the volatilization of the materials, improving the wettability with respect to the water cooling rollers in the process of preparation, and the material finally prepared has a relatively good magnetic performance. |
