Why diamond has a higher melting point than silicon carbide?

The bond energy of Si -C is generally considered to be lower than that of the C-C, so a simple explanation is that diamond has a stronger bond. Both diamond and silicon carbide have a three dimensional network structure. Diamond consists of tetrahedral bonded carbon atoms whereas silicon carbide has many polymorphs (crystal structure which are temperature dependant). As you heat silicon carbide up the crystal structure changes. Silicon carbide does not melt "congruently" to give a liquid of the same composition, it decomposes at around 2700 0C .
