Graphite has a wide variety of almost contradictory uses. An allotrope of carbon and one of the world’s softest minerals, its uses range from writing implements to lubricants. It can be made into a one-atom-thick cylinder of graphene that is a super-strength material used in sports equipment. Graphite can behave like a metal and conduct electricity but also as a nonmetal that resists high temperatures.

Crystalline Structure

Graphite occurs naturally as flakes and veins within rock fractures or as amorphous lumps. The basic crystalline structure of graphite is a flat sheet of strongly bonded carbon atoms in hexagonal cells. Called graphenes, these sheets stack above each other to create volume, but the vertical bonds between the sheets are very weak. The weakness of these vertical bonds enables the sheets to cleave and slide over one another. However, if a graphene sheet is aligned and rolled horizontally, the resultant material is 100 times stronger than steel.

Writing and Artists' Materials

“Lead” pencil cores are made of a mixture of clay and graphite. Loosely cleaved graphite flakes mark the paper, and the clay acts as a binding material. The higher the graphite content of the core, the softer the pencil and the darker its trace. There is no lead in what are known as lead pencils. The name originated in Europe when graphite was called “plumbago” or “black lead” because of its metallic appearance. Graphite’s use as a marker dates from the 16th century in northern England, where local legend states that shepherds used a newly discovered graphite deposit to mark sheep.
