Large quantities of carbon can be found in the sun and in the atmosphere of most planets. Although on the earth the content of carbon is less than 0.1 percent, it still is the basis of organic chemistry and of life itself. This is because of carbon's property to form composites with itself and with other elements such as oxygen, hydrogen, or nitrogen. Crystalline carbon is only known in five allotropic forms:
GRAPHITE, DIAMONDS, FULLERENES, NANOTUBES and GRAPHEN
Types of Graphite
Graphite is chemically inert, eco-friendly, and absolutely safe. It is classified as microcrystalline and macrocrystalline natural graphite and synthetic graphite. Six hexagonally arranged carbon atoms form the basic unit of the graphite crystal. The twodimensional lattices are highly stable within themselves, but they can be easily shifted against each other.
