Quick Answer: Why Does Silicon Carbide Have A High …

2021-10-12 · Why does silicon carbide have a high melting and boiling point? Hence the metallic bond increases in strength and needs more energy to be broken, and so a higher melting point. 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.
