Silica (Silicon dioxide) is a very interesting system, sharing many similarities with the physical properties of water.
Models[edit]
Beest, Kramer and van Santen (BKS)[edit]
Woodcock, Angell and Cheeseman (WAC)[edit]
Phase diagram[edit]
Critical point[edit]
Temperature of maximum density[edit]
Silica has a temperature of maximum density (TMD) [8] [9]
Polymorphism[edit]
Silica has a number of crystal structures. [10]
Polyamorphism[edit]
Silica has a polyamorphic (liqid-liquid) phase transition [11] [12] [13]. A recent study has concluded that neither the BKS nor the WAC models have a critical point [14].
