Synthesis of Nanomaterials by High Energy Ball Milling

For all nanocrystalline materials prepared by high-energy ball milling synthesis route, surface and interface contamination is a major concern. In particular, mechanical attributed contamination by the milling tools (Fe or WC) as well as ambient gas (trace impurities such as O 2, N 2 in rare gases) can be problems for high-energy ball milling

Effect of ball-milling time on mechanical properties of

After long time (6–8 h) ball-milling, nearly no CNT clusters could be found on the surfaces of the Al powders and many CNTs with tips outside the Al powders could also be observed, as shown in Fig. 3c and d, indicating that most of the CNTs were dispersed into the Al powders. A schematic of CNT distribution during ball mill is shown in Fig. 4
