Silicon carbide - Wikipedia

Silicon has a very high melting point due to its giant covalent structure; a lot of energy is needed to break the strong covalent bonds throughout the structure. 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).
