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.

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.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
