Carbon nanotubes were treated by highenergy ball milling processing for different milling times, and the samples were observed by HRTEM. The broken nanotubes and lots of carbon onionlike particles were obtained in the sample milled for 15 min. When the milling time was up to 60 min, carbon nanotubes turned into amorphous carbon.
Ball Milling. Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.
