Specific questions about permanent magnet production

  1. Jun 25, 2009 #1
    I would like to know if anyone here has ever been involved in permanent magnet production, and more specifically, with the sintering process. What temperature must a NdFeB magnet be heated to for sintering and also, how do you determine the length of time you sinter for? What kind of density increases are typically observed post sintering?

    Also before the sintering stage, after the material has been compressed, is it safe to handle the compressed ore without it crumbling apart, or must the compressed shape be kept in the die for the sintering process?
