摘　　要：以-325目球形锌粉为原料,采用高能球磨法对片状锌粉的制备方法进行研究,考察球料比、球磨时间对片状锌粉性能的影响。结果表明:在球磨时间相同条件下,随着球料比的增大,锌粉粒度、松装密度也不断降低;在球料比相同条件下,随着球磨时间的延长,片状化程度不断增大,球磨时间达到16~20 h之间,比表面积不再增加而略有下降。-325 mesh spherical zinc powder is the raw material,high energy ball milling is adopted for preparation of flake zinc powder,for investigation of ball percentage,the effect of ball-milling time on flake zinc powder performance. The results show： under the same ball-milling time,the particle size,apparent density of zinc powder is decreasing constantly along with the ball percentage increasing;under the same ball percentage,the flake degree is increasing constantly along with the prolonged ball milling time,when the ball milling time reach to 16 - 20 h,the specific surface area could not increased but has a little reducing.
