WebApr 4, 2024 · Graphite is a soft, black, lustrous mineral composed of carbon in a hexagonal crystalline structure. It is found in three different forms: in high-grade metamorphic rocks as disseminated crystal flakes; in veins or fractures as vein graphite; and in thermally metamorphosed coal deposits as amorphous graphite. WebThe graphite that remains links into a sheet-like crystalline structure. Synthetic graphite can have a purity of over 99% carbon, and it is used in manufactured products where an extremely pure material is required.
