A thermodynamic assessment of silica phase diagram

An internally consistent data set on the thermodynamic properties of the silica polymorphs stable up to 15 GPa (α-quartz, β-quartz, tridymite, cristobalite, coesite, and stishovite) and the liquid phase is presented. The data set was produced through a computer-based assessment of the properties in which the available thermochemical (calorimetric), physical (bulk modulus and thermal expansion), and solid-state and melting transition data (including some newly determined data on the high-pressure polymorphs coesite and stishovite) were considered
