As listed in Table 3221, substances with large bonding energies usually have high melting temperatures.

Table 3221. Bonding energies and melting temperatures of ionic substances.

Bonding type
Substance
 Bonding energy
Melting point (°C)
kJ/mol kcal/mol eV/Atom, Ion, or Molecule
Covalent
 Typical value 200-1000      
Si 450 108 4.7 1410
Diamond C 713 170 7.4 >3550

Note that page3239 describes the correlation between the bonding energies and melting temperatures of different substances.
