摘　　要：用气流研磨法制备出了球形度达到0.95以上的致密B4C微球,从理论上得出了颗粒形状与气流速度的关系。Micro B4C spheres with an average sphere factor of 0.95 has been prepared by the gas grinding method. And the theoretical relationships between the product shape factor and gas velocity has been derived. It is shown under an appropriate gas velocity, to prolong the grinding time can make the product sphere factor larger than 0.95.
