Graphite (CAS number 7782-42-5), one of the most stable forms of carbon under standard conditions, is a naturally occurring form of crystalline element carbon.

Graphite powders possess many unique physical and chemical properties such as refractoriness, high structural strength at high temperature, high thermal shock resistance, high thermal and electrical conductivity, low thermal expansion, and good chemical resistance. Graphite has both metallic and non-metallic properties and is readily soluble in iron. The combined unique property of graphite makes its wide applications from common pencils, zinc-carbon batteries, lubricants, paints, welding rods, desulfurizing agents, facings, refractories, marking instruments, batteries, bearings, conductive coatings, and crucibles to electrodes.

With such high purities, graphite powders are also suitable for liquid exfoliation or intercalation to either produce single layer/few layers graphene nanosheets or fill the spaces with cations i.e., Li+ between the layers of graphite.

Each carbon atom in diamond (left) has bonds extending in 3 dimensions - meaning that when diamond is cut in any orientation, some of these bonds must be broken and are left 'dangling' (shown in red). The atoms in graphite (right) have bonds extending in only 2 dimensions, so when it is cut in an orientation parallel to the bonds, none of them are broken.
