Graphite hexagonal molecular structure, illustration
Graphite hexagonal molecular structure, illustration. Graphite is a form (allotrope) of the element carbon. It takes the form of regularly repeating units with the hexagonal structure shown here. Graphite is used in pencil leads and as a lubricant. It is composed of parallel layers of hexagonally arranged carbon atoms (spheres). Within each layer the carbon atoms are linked by strong covalent bonds, while the parallel layers are linked together by weak Van der Waals' forces. This Van der Waals' bonding is strong enough to hold the layers together, yet weak enough to let them slide over each other. This results in graphite's softness and its ability to act as a lubricant. For illustrations showing the extended repeating structure, see images C042/4534 to C042/4537.
