The structural composition of carbon graphite is mainly composed of carbon atoms, and its crystal structure is hexagonal layered. In graphite crystals, carbon atoms in the same layer form covalent bonds with sp2 hybridization. Each carbon atom is connected to three other carbon atoms through three covalent bonds, forming a honeycomb-like layered structure. These layers are composed of coplanar six-membered rings and C-C bonds, which are called graphene.
Physical properties of graphite
Graphite is opaque and greasy to the touch. Its color ranges from iron black to steel gray. Its shape can be crystalline, flake, scaly, striped, or layered. The relative density of graphite is 2.256 g/cm³.
