Ball milling has been extensively used for carbonaceous materials to study the structural changes with change in milling time 6 Recently there was a report on synthesis of bi layer graphene by ball milling graphite 7 Ball milling has been used for each type of carbon materials such as .
Layered LiNi0.4Mn0.4Co0.18Ti0.02O2 cathode powders were ball-milled for various lengths of time. The structural properties of the pristine and milled powders, which have different particle sizes were examined with X-ray diffraction, soft X-ray absorption spectroscopy, and transmission electron microscopy to determine the effect of milling on .
Phase transformations of -FeCr induced by ball milling B. F. O. Costa J. M. Loureiro G. Le Car Published online 9 November 2006 Springer Science Business Media B.V. 2006 Abstract A tetragonal sigma phase -Fe 0.54Cr 0.46 transforms gradually into a bcc phase by ball-milling in argon. Mssbauer spectroscopy shows further the presence of an amorphous.

Low-cost, high-yield production of graphene nanosheets GNs is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite ECG by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer 5 layers GNs.
