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.
Certain applications such as mechanical seals require a certain degree of rubbing abrasion to provide the necessary “lapping” or cleaning of opposing rubbing surfaces. The ash content of amorphous graphite can provide the right balance of gentle abrasion required to perform this function. By selecting a properly sized amorphous graphite powder the user can control the size of the ash.
Grades are categorized based on particle size and purity and can be customized to fit any requirement.
