Jan 24 2012· Graphite Graphite is a dark gray to black mineral with a metallic luster it has relatively low hardness 0 51 in Mohs However because of graphite s often occurrence as flakes and the covalent bonds strength within the sheetlike graphene it is very hard to grind graphite to fine particle size For sizes above 100 microns most hammer
The invention is related to a method for producing flake graphene by direct exfoliation of graphite, characterised in that it comprises the following steps: a) an aqueous suspension of graphite with addition of one or more surface active agents is prepared; b) the suspension is frozen; c) the suspension is dried, thereby obtaining flake graphene.

Crystalline flake graphite can be divided into two main grades: coarse flakes (≥150850 µm in diameter) and fine flakes (≥45150 µm in diameter), which may be further subdivided into
mm. Most graphite flakes are oblong shaped, but not particularly fibrous, and the ratios between their long and short axes are in the range of 2 to 4 for the majority of the flakes. These results are typical for Jennestad graphite and are also characteristic of a coarse, highquality, flake graphite ore. The results of the graphite morphological
