Natural Flake Graphite

Natural flake graphite is a crystalline carbon, natural, non-metal, black or dark grey mineral. It is soft and greasy. It belongs to hexagonal crystal system. It is foliaceous, scaly or compactly lump. Flake graphite has a density of 2.23 g/cm3, melting point of 3625 °C.
 
The particle size ranges from 75 µm to 500 µm, and the carbon content ranges from 80 to 99.99 %. According to the customer’s needs, we are able to offer high carbon, medium carbon and high purified flake graphite, too.
 
Flake graphite is widely used as an essential non-metallic in almost all industries. After further processing, crystalline flake graphite can be used to produce TV tube coatings, graphite friction reducing additives and many other high-tech products.
