It is demonstrated that unique carbon nanostructures including carbon nanotubes and carbon onions are synthesized byhigh-speed ball-millingofsteel balls. It is considered that the gas-phase reaction takes place around the surface ofsteel ballsunder localhigh temperaturesinduced by thecollision-friction energyinball-millingprocess, which results in phase separated unique carbon nanomaterials.
