For all nanocrystalline materials prepared by highenergy 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 highenergy ball milling

Sep 16 2013 the statistical analysis of the length distribution of catalytic chemical vapour deposition synthesized multiwalled carbon nanotubes cut by planetary ball milling is reported the nanotube lengths follow a lognormal distribution in a broad range of grinding time and rotational speed we show that the scale parameter of the distribution which equals the mean of the natural logarithm of the

The ball milling times was correlated to the resulting microstructure and ultimately its thermoelectric performance it was found that the moderate milling times at 15 h resulted in the best electrical conductivity given the homogenous distribution of particles nanowires quantum dots and molecular engineering of crystalline

The above milling experiment was carried out at fritsch pulverisette 6 planetary highenergy ball milling system in the air with room temperatures for different times a 250 ml stainless steel carbide vial with 10 stain less steel balls along with a diameter of 20 mm was used as a milling medium the milling speed was set at 370 rpm
