The difference between this two is due to the structures of these oxides. Carbon dioxide molecule consist of double bonds between carbon and oxygen atoms.this provides the molecule a linear shape. the main force of attraction between the atoms is weak van der Waals force.in comparison,the SiO2 molecule is very different. Each silicon atom is surrounded by 4 oxygen atoms and there are only single bonds between the silicon and oxygen. this silicon-oxygen linkage provides it with a networked structure where many atoms are connected to each other i.e. a single oxygen atom is shared between multiple silicon atoms
