Natural Flake Graphite

Graphite flake may form under pressures of 75 000 psi (1GPa) and 1380 deg F (750 deg C) Since graphite is a form of carbon and all carbon oxidizes at high temperature a geologic environment in which nascent or otherwise reactive oxygen is present will preclude the formation of graphite Graphite must have a reducing environment in order to

What is the differences in physical properties of Diamond

In graphite there are large spaces between adjacent layers due to weak forces between them On the other hand in diamond atoms are held by strong covalent bonds and relatively more closely packed Hence diamond has higher density than graphite Density of diamond is 3510 kg/m 3 whereas that of graphite is 2250 kg/m 3
