Introduction - Graphite

Graphite has been in use since the 15th century. Pencil marking is formed by sheets of graphite sliding off and settling onto the paper. However, now, graphite has found use in many different applications other than as a writing tool.

Characteristics of Graphite

Graphite is composed of extremely strong fibers made of series of stacked parallel layer sheets. The material is black in color and optically opaque. It is inert to weathering and demonstrates softness graded below talc. It is used for applications in paints, carbon additives, electrical brushes, conductive coatings, batteries, dry-film lubricants, lubricating oils and greases thanks to its greasy friction-resistant properties.

Graphite is a representation of a typical layered polymeric crystal, where each fullerene acts as a molecule to form molecular crystals (fullerites). In graphite, the covalent bonding of each carbon atom to three other carbon atoms provides a trigonal geometry to the material. Bond angle in the material is 120° and each carbon atom is sp2 hybridized. Three out of four valence electrons of each carbon atom are involved in the formation of covalent bond with three other carbon atoms, whereas the fourth electron freely moves in the structure of the material.

The basic hexagonal ring is a result of the combination of basic trigonal units. The C-C bond length in the hexagonal ring is 1.42 Å. These rings create flat layers in graphite. These layers are stacked in parallel, one above the other. These layers are at a distance of 3.35 Å and are connected through weak van der Waals forces only. Since these layers can slide over each other, the material is very soft. Fourth electron of each carbon atom creates delocalized p-bonds, which spread homogeneously over all carbon atoms. This allows the graphite to conduct electricity in the direction parallel to its planes.
