Amorphous Graphite. Amorphous graphite is the least graphitic among the natural graphites. However, the term “amorphous” is incorrect as the material is still crystalline. Amorphous graphite can be found as minute particles in beds of mesomorphic rocks such as coal, slate, or shale deposits. The graphite content varies from 25% to 85% ...
Types of Graphite: Amorphous, Flake and Vein – …
Types of Graphite: Amorphous graphite. Amorphous graphite is found as extremely small, crystal-like particles in beds of mesomorphic rocks like coal, slate and shale, and its carbon content depends on that of its parent material. When found in coal, it is the result of the thermal metamorphism of coal and is referred to as meta-anthracite.

Europe Amorphous Graphite Market Size, Status and …
2020-12-25 · Amorphous Graphite is very fine flake graphite. It has a soft black earthy appearance with crystal sizes of less than 40µm and a high ash content. Amorphous graphite is formed by the metamorphism of anthracite coal seams that may be hosted by quartzites, physllites, metagreywackes and metaconglomerates.
