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.

high-energy ball milling - RUSNANO. High-energy ball milling is a simple, effective and productive way to produce various nanocrystal powders in high-energy planetary, ball and vibratory mills.Other things being equal, the higher the intensity and duration of grinding and the smaller the weight and size of particles of milled source powder, the smaller the average size of the powder particles.
