Lubriing properties of graphite materials - Graphite

The good lubricity of graphite materials originates from the crystal structure of its own lamellar structure. In the layered graphite crystal structure, carbon atoms form hexagonal graphite layer with SP 2 hybrid orbital. The bond energy between carbon and carbon belongs to a resonant σ- bond ( σ- electron covalent bond), which can reach 627KJ/mol.

Why is the bond length of diamond greater then that …

Graphite is layered. Within each layer, carbon atoms form strong covalent bonds in a hexagonal pattern (planar). A covalent bond is one in which one or more pairs of bonding electrons (valence) are shared. Carbon forms a double covalent bond, which means that two pairs of bonding electrons are shared. This type of bond is very strong.

Graphene - Wikipedia

2019-4-26 · Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice.. Graphene can be considered as an indefinitely large aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons. Graphite, the most common allotrope of carbon, is basically a stack of graphene layers held together with weak bonds.
