Graphite is a kind of crystalline carbon.Hexagonal crystal system,from iron ink to dark gray. soft,slippery
It's feature is high temperature resistance,conductivity,thermal conductivity,lubricity.
Earthy graphite: is also called microcrystalline graphite.Earthy graphite has good quality,high fixed carbon content,few harmful impurities,and extremely low sulfur and iron content.
Flake graphite:Flake graphite graphite crystals are flake like,they are transformed under high intensity pressure,and can be divided into large scales and fine scales.It is one of the best floatable minerals in nature.
Expandable graphite: Fireproof adhesive tape.
It is widely used to oil field drilling,battery carbon rod,cast steel material,electrode paste,pencil,Lubrication, paint added, Refractory (fire resistance greater than 2000° C) , battery additives, raw materials for making graphene, electrical conductivity, foundry industry, fertilizer coating, etc.
