Amorphous Graphite Asbury Carbons

Amorphous graphite is a seam mineral, not to be confused with a vein mineral. It is formed by the metamorphism of previously existing anthracite coal seams. Proto-coal organic carbon is deposited and converted into anthracite coal followed by low grade metamorphism of the coal. This results in the formation of microcrystalline graphite.

Amorphous Graphite from stock or special order. USA

Amorphous graphite is a natural mineral. Contrary to the name, this is not truly amorphous, but is a microcrystalline form of natural graphite. It is granular except in extremely fine grinds, which have a flakey structure. The term “amorphous” is applied to this form of natural graphite. Material is available in sizes ranging from mixed 1 ...

We predict the three-dimensional structure of amorphous carbon generated by heating diamond superlattice at 6000 K with rapid quenching from the liquid phase for densities ranging from 2.0 to 3.5 g/cm 3, in comparison with 2.26 and 3.54 g/cm 3 for bulk graphite and bulk diamond, respectively. These predictions are based on reactive dynamics (RD) simulations using the ReaxFF reactive force field.
