beskrivelse:

Theoretical phase diagram of carbon, which shows the state of matter for varying temperatures and pressures. The hatched regions indicate conditions under which one phase is metastable, so that two phases can coexist. The source reference says that the phase diagram is well established only up to around 100 GPa. More recent work shows that the melting point does not go as high as 10,000 K. Accurate illustration but not a pixel-exact plot. Also note that a considerable disagreement exists between theory and experiment, e.g., for the triple point doi:10.1016/0008-6223(76)90010-5
