ball milling for graphite grounding

Ball Milling - an overview | ScienceDirect Topics

Highly ordered synthetic graphite was mechanically ground in a planetary ball mill. The interlayer spacing d 002 was found to increase in the grinding process with the reduction of the crystalline size L a, L c.The specific surface area increased to over 600 m 2 /g at the maximum. The result of Raman spectroscopy shows that the ground graphite yields a smaller value of full width at half ...
