Graphite Powder - High Purity Crystalline Material, Excellent Electrical Conductivity And Lubricating Properties

We are engaged in offering excellent quality Graphite Powder to our valuable clients. Graphite is a crystalline solid of black-grey colour with a metallic sheen, whose structure, described by Hull [1], corresponds to a stacking of planes of carbon atoms, that are bonded to each other by covalent bonds with sp2 hybridization. In a layer or plane, the atoms are arranged according to a hexagonal pattern and thus constitute what is called a a graphene sheeta . On the other hand, the interactions between the planes of graphite are weak, due only to Van der Waals forces. This facilitates the a slipa of the planes onto each other, when mechanical pressure is applied. This property of graphite, of being easily cleaved along the graphene sheets, is mainly responsible for its lubricating properties. Due to its electronic structure, graphite shows a high electrical conductivity. It can reach 25a 000 S/cm [2] in the plane of a single-crystal. In dense polycrystalline graphite materials, conductivity is in the range of 1a 000 S/cm [3] and the anisotropy factor is reduced to a few units at the most. Thanks to its chemical (layered) and electronic band structure, graphite is an ideal host for the intercalation of certain atoms. Depending on the type of atoms, i.e. reducing metals [4] or acidoxidizing molecules [5], one speaks of a intercalation compoundsa or a graphite saltsa , respectively. Clients can avail this Graphite Powder at industry leading prices from us.
