利用滚压振动磨对石墨进行研磨，并用XRD、拉曼散射、SEM和BET对产物的结构和形貌进行了研究。实验表明，随着研磨时间的增加，石墨晶粒尺寸减小，原有的晶体结构被破坏，引入大量缺陷。石墨在研磨10 h后呈厚度为纳米级的片状，而且石墨化度变化不大。实验同时为短时间制备高纯度的纳米石墨提供了一个新的方法。

Well-crystalline graphite was ground by roller vibration milling for different milling time,and the samples were examined by XRD,Raman scattering,SEM and BET.The result indicated that the grain size of graphite declined as milling time increasing,and a great many of defects were induced with the destruction of the structure of the pristine well-crystalline graphite.High graphitization degree of graphite nanosheets were expected after milling for 10 h.This provided a new method of preparation of nanographite with high purity in a short time.
