Google Scholar WebSilicon dioxide (SiO2) has a macromolecular structure. This means that it forms thousands of covalent bonds between its silicon and oxygen subunits. Since covalent bonds require more energy to overcome than van der waals, SiO2 requires a higher temperature than SO3 to melt, thus SiO2 has a higher melting point. 2.
