Viscosity and Glass Transition in Amorphous Oxides

Temperature dependence
of the order parameter of configurons in (a) amorphous SiO2 (b) and GeO2 [6]. The liquid phase
seems more ordered for configurons (broken bonds) which are largely a part of
the percolation cluster in the liquid whereas in the glassy phase the
configurons are randomly distributed in the solid.
