Ball milling carbon

Timcal Ltd. (Super C65), and carbon nano tubes supplied by Sigma-Aldrich (Multi-Wall Carbon Nano tubes). The ball milling was carried out in a conventional planetary ball mill as well as in a high-energy ball mill. For graphite, our goal is to investigate the ball mill effect, so a high-energy ball mill was used to maximize the change
