Why is Silicon dioxide macromolecular? | Yahoo Answers

17/4/2008· Consequently the only intermolecular forces in pure carbon dioxide are London dispersion forces. The electron structure of SiO2 is very different. Unlike CO2, where there is excellent overlap between carbon and oxygen 2px orbitals and between 2py orbitals, there is very poor overlap between the silicon 3px and 3py orbitals and the oxygen 2px and 2py orbitals.

Figure Figure4 4 also represents the chip morphology of β-silicon carbide (cubic) during the nanometric cutting process against a deformable diamond tool. It can be seen from Figure Figure4 4 that the cutting chips are curly shaped, which suggests that material removal is occurring in ductile regime by deformation rather than fracture.
