The parameters for perparation of spherical agglomerated boron particles with solvent evaporation process were optimized by orthogonal experiment. The effect of curing temperature and curing time on the appearance and distribution of particle size of spherical agglomerated boron particles were studied. The spherical agglomerated boron was characterized by SEM. The results show that the spherical agglomerated boron particles prepared by the optimum preparing method were smooth, regular in morphology.The optimum conditions are:stirring rate, 70 r/min; solidified time, 7 days; temperature,20℃;mass ratio of B and binder,9∶1; curing temperature,70℃.
