It is a natural vein mineral formed from the geological metamorphism of anthracite when making contact with a metamorphism agent, for example: tectonic stress, magma, etc. The result is a microcrystalline graphite, which is commonly called amorphous graphite.
This type of natural graphite is called amorphous because microscopic graphite crystals are not visible to the naked eye and as a result have an amorphous appearance.
Amorphous graphite contains 60% to 85% of fixed carbon. It is the most common type of graphite and is used in many lubricating products such as grease, forging lubricants, etc.
In applications where high ash and low carbon content is acceptable, this type of graphite is a good choice. It has an exceptional value for engineering solutions that require graphite material at an affordable price.
