Graphite doesn't have a distinct melting point in the way that many other substances do. Instead, it sublimes at very high temperatures. This means that it transitions directly from a solid to a gas, skipping the liquid phase.

Here's what we know about graphite's transformation at high temperatures:

* Sublimation point: Around 3652°C (6606°F) at atmospheric pressure.

* Melting point under high pressure: Under extreme pressure (over 100,000 atmospheres), graphite can melt at around 4200°C (7592°F).

It's important to note that these are approximate values and can vary slightly depending on the purity and specific conditions of the graphite.
