Carbon - Wikipedia

At atmospheric pressure it has no melting point, as its triple point is at 10.8 ± 0.2 MPa and 4,600 ± 300 K (4,330 ± 300 C; 7,820 ± 540 F), so it sublimes at about 3,900 K (3,630 C; 6,560 F). [21] [22] Graphite is much more reactive than diamond at standard conditions, despite being more thermodynamically stable, as its delocalised pi system is much more vulnerable to attack.
