Properties of graphite: density and mechanical properties

Density: Crystallographically perfect graphite has a density of 2.265 g/cm3. Density can give a measure of crystal perfection and in practice, synthetic graphite rarely exhibits a density above 2.0 g/cm3 with some versions as low as 1.6 g/cm3. The density of synthetic graphite is directly related to the pore size and decreasing the particle size, or grain, reduces the relative porosity
