Why does graphite have a higher melting point than diamond ...

However, if you look closely at the diagram, you will realize that at a little less than 100,000 atmospheres, where graphite is stable, its melting point is also 4200 K. So the short answer is that there is no difference in the melting points of graphite and diamond at the same pressure.

Carbon - Wikipedia

Carbon sublimes in a carbon arc, which has a temperature of about 5800 K (5,530 °C or 9,980 °F). Thus, irrespective of its allotropic form, carbon remains solid at higher temperatures than the highest-melting-point metals such as tungsten or rhenium.
