US7993621B2 - Surface preparation of natural graphite and ...

Natural, graphite having an initial particle size of 375 μm is ground by a process of air-milling until the particles attain a size of 10 μm. The graphite is then leached in a mixed aqueous bath comprising 30% H 2 SO 4 and 30% HF. 106.5 ml of the mixed acid is heated to 90° C., and 30 g of graphite is then added into the solution.

Natural graphite was ball milled in a vibratory and a planetary mill under different atmospheres. Its microstructure was found to evolve very differently when milled in oxygen and in an inert atmosphere. This phenomenon is most pronounced when it was milled in a planetary mill where the deformation forces are mainly shear in nature.
