Considerating over-all performance of mag nets, it was concluded that the optimal amount of doped-Ga was 0.5wt%. The other was that the grains size distribution of grains was narrow and grain distributed homogeneously as to microstructure of magnets when the amount of doped-Ga was 1 .Owt%;(3 ) In the magnets, there existed not only Nd2Fei4-xGaxB, but also GaNd concerning the Ga-elment form. The GaNd increased the amount of liquid and had favorable function during sintering, so it made for the increase of magnets density and the form of the second phase is good for improving coercivity.
