ball-milling: the behavior of graphite as a function of

fig. 9 gives the xrd diagrams before ball-milling (a) and after 12 h (b) of grinding with balls of 5 mm. the graphite remains well organized even after a longer milling duration but the rhomboedral content (pointed out by the asterisk on the xrd diagram) increased from 8% for starting graphite powder to 12 and 20% after 12 and 48 h respectively.

unexpected colloid-like supernatant from s liquid-phase

powder properties of hydrogenated ball-milled graphite

abstract. ball milling is an effective way of producing defective and nanostructured graphite. in this work the hydrogen storage properties of graphite ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0–40 h) were investigated by tga-mass spectrometry xrd sem and laser diffraction particle size analysis.

exfoliation of graphite by dry ball milling with cellulose

dry ball milling of graphite with cellulose and related polysaccharides was found effective for exfoliation-dispersion of graphene-like carbon. the exfoliation behavior was found to depend strongly on the species; namely polysaccharides are much more effective than thermoplastic s.
