$\begingroup$ I think, for the most part, designing a separation procedure depends on you knowing the chemical identity of the two compounds. Like if you have AgCl and AgBr (not exactly a white powder, but I'm just trying to make a general point) you can separate them by addition of ammonia.

A review of exfoliated graphite SpringerLink

Jul 26, 2015  Exfoliated graphite (EG) refers to graphite that has a degree of separation of a substantial portion of the carbon layers in the graphite. The process that results in this separation is known as exfoliation [], which can involve chemical, mechanical, and thermal methods.The separation occurs between adjacent carbon layers, but typically not all the carbon layers are separated.

Graphite Structure Asbury Carbons

Graphite is composed of layers of carbon atoms that are arranged in 6-membered, hexagonal rings. These rings are attached to one another on their edges. Layers of fused rings can be modeled as an infinite series of fused benzene rings (without the hydrogen atoms).

Graphite powder and flakes have a higher density than SAT. The graphite will separate from the PCM and settle to the bottom of the container if no precautions are taken. Mixtures of 200 g SAT with 1%, 2.5% and 5% CMC and SAT with 0.25%, 0.5% and 1% xanthan rubber (all weight %) were prepared without graphite.

Mar 28, 2017  The thinnest to thickest graphene dispersions exist in this order: graphite oxide, graphite sooth, graphite powder and graphite rod. We believe the reason for this order is because graphite oxide is processed with strong acids to increase the separation of graphene layers thereby making it easy for exfoliating agent to break the bonds.

Graphene - Wikipedia

Structure of graphite and its intercalation compounds. In 1859 Benjamin Brodie noted the highly lamellar structure of thermally reduced graphite oxide. In 1916, Peter Debije and P. Scherrer determined the structure of graphite by powder X-ray diffraction. The structure was studied in more detail by V. Kohlschütter and P. Haenni in 1918, who also described the properties of graphite oxide paper.

Properties of graphite: density and mechanical properties ...

Density: Crystallographically perfect graphite has a density of 2.265 g/cm3. Density can give a measure of crystal perfection and in practice, synthetic graphite rarely exhibits a density above 2.0 g/cm3 with some versions as low as 1.6 g/cm3. The density of synthetic graphite is directly related to the pore size and decreasing the particle size, or grain, reduces the relative porosity ...
