摘　　要：论述了爆轰法制备纳米石墨 ,并对其进行了 X射线衍射分析、BET比表面分析和透射电子显微镜分析。测试分析结果表明 ,爆轰法制备的纳米石墨微粉晶粒度为 0 .85 nm,颗粒分布约为 6 0 nm以下 ,有团聚现象。The nano-graphite was synthesized by detonation in a sealed vessel. The characteristics of the nano-graphite were analyzed, including X-ray diffraction, BET and TEM. The results show that the diameter of the nano-graphite was 0.85nm. The average size of the particle is below 60nm and the particles show reunion phenomenon.
