Molecular dynamics simulation of graphite melting

High Temperature. 2014. Vol. 52. No. 2. P. 199-205.
Orekhov N., Stegailov V.

Questions on the behavior of the graphite melting curve have remained open during the last fifty years. The process of graphite melting in the pressure range of 2–14 GPa is investigated by the method of molecular dynamics using the model of reactive interatomic potential; the dynamics of meltingfront prop agation upon crystal superheating is considered, and the melting curve is plotted. The selfdiffusion coefficient in the liquid phase is determined for the aforementioned pressure range, and the question of the existence of the liquid–liquid phase transition in carbon is considered.
