Production mannered null constitutional formula M of permanent

摘要

PROBLEM TO BE SOLVED: To provide a permanent magnet, having improved magnetic performance by heating a pulverized magnetic powder for recycling the surface of magnet particles, and to provide a method for manufacturing the permanent magnet.SOLUTION: The coarsely pulverized magnetic powder is pulverized with a bead mill in a solvent, together with an organic metal compound equivalent to M-(OR)(wherein M is V, Mo, Zr, Ta, Ti, W or Nb, R is any one of 2-6C alkyl groups and may be a straight chain or a branched chain, and x is an arbitrary integer), and the organic metal compound is uniformly deposited to the surface of the magnetic particles. After that, the dried magnetic powder is maintained for several hours at 600-1,000°C in a low-oxygen atmosphere, thereby recycling each of the magnetic particles forming the magnetic power 43. Furthermore, the recycled magnetic powder is molded and baked at 800-1,180°C, thereby a permanent magnet 1 is manufactured.
