I thought that SiO2 would have a higher melting point than MgO because it forms a giant covalent structure whereas MgO only forms a giant ionic structure but this isn't the case as the melting point for MgO is higher. can someone tell me why?

The ionic bonds in MgO must be stronger than the covalent bonds in SiO2.
