    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.
