Abstract: Carbon aerogel ultrafine powders were prepared by ball-milling method. The effects of preparation parameters such as ball-milling time, quantity ratio of ball-sample and addition of grinding aid, on the properties of products were systematically investigated. The results show that the proportion of large particles in particle size distribution of products decrease with increasing in ball-milling time, but the ball grinding time above 4 h has little influence on small particles, and that Dv(50) in particle size distribution of products first decrease and then increase with increasing in mass ratio of ball-sample, the lowest Dv(50) value is 2.58 μm when the mass ratio is 50∶1, and that the particle size of products increase with the addition of the solutions of grinding aids and the influence of different grinding aids is different.
