Why Diamond has higher melting point than Silicon …

Silicon carbide sublimates at about 2700 °C. Explanation The difference appears to be caused by the differences in bond lengths and bond strengths. 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).
