Ball milling and annealing graphite in the presence of

Abstract When graphite is ball milled, Raman spectra and X-ray diffractograms of the products show increasing graphitic structural disorder with 1% and 10% cobalt addition. However, if sufficient cobalt (10% weight for weight) is added, this process is reduced in rate. This process is attributed to the cobalt stabilizing the graphitic structure during ball milling, thus reducing the degree of ...

In plane defects produced by ball milling of expanded graphite

In plane defects produced by ball milling of expanded graphite

During the milling process (up to 100 h), the crystallite size ( L c ) of EG decreases gradually from 15.4 to 11.3 nm. Compared with most of natural graphite, this L c decrease degree of EG is far lower. In the EG after ball-milling for 100 h, plenty of in-plane defects are produced, which rarely occur in most of ball-milled natural graphite.
