Question: Why Does Silicon Carbide Have A High …

Why does diamond have a higher melting point than silicon carbide? Silicon carbide has a C-Si bond length of 186 p.m. and a bond strength of 318 kJ/mol. Diamond has a much shorter C-C bond length (154 pm) and stronger bonds (348 kJ/mol). Thus, it takes more energy to vaporize diamond, and diamond has the higher sublimation temperature.
