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.

综合考虑磁体的性能，最终得出添加0.5wt％为最佳的Ga添加量；(2)对于Nd_(15)Fe_(78)B_7+Ga系永磁体，当Ga的添加量为1.0wt％时，得到颗粒粒度分布范围窄，颗粒分布较均匀的显微结构；(3)元素Ga在磁体中不但以Nd_2Fe_(14-x)Ga_xB形式存在，而且以GaNd的形式存在，在烧结的过程中，增加了液相的数量，起助烧结的作用，有利于磁体密度的提高，形成第二相有利于矫顽力的提高。
