The pressure-induced structural changes in liquid SiO2 from Ab Initio simulations were discussed. It was found that the liquid SiO2 became denser than quartz at a pressure of about 6 GPa in agreement with extrapolations of lower pressure experimental data. The analysis showed that the changes consist in an increase of network connectivity caused by the pressure-induced appearance of coordination defects.
