Graphite has no melting point, and instead turns into gas at 6254 degrees Fahrenheit through the process of sublimation. Graphite is entirely made up of the element carbon.
Graphite is chemically similar to diamond, but the two substances are physically different. One point of difference lies in the hardness of each material. Using the 1 to 10 Mohs scale of mineral hardness, graphite registers at 1 to 2 due to its softness, while diamond ranks as the hardest substance at 10. While diamond's hardness is credited to its covalently bonded electrons, graphite's softness results from its sliding sheets of carbon atoms.
