Two processes occur in the Si–O–C system: (i) crystallization of phase separated

Question: Why Does Silicon Carbide Have A High Melting …

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.

Silicon - Wikipedia

Silicon compounds such as silicon carbide are used as abrasives and components of high-strength ceramics. Silicon is the basis of the widely used synthetic polymers called silicones . The late 20th century to early 21st century has been described as the Silicon Age (also known as the Digital Age or Information Age ) due to elemental silicon having a large impact on the modern world economy.
