Product details
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. However, unlike coal, amorphous graphite is not used as fuel as it is difficult to ignite.
According to Riddle, amorphous graphite that is marketable today typically ranges in purity from 70 to 90 percent.
