High-silica zeolites are 5.6-15.5 kJ/mol less stable in enthalpy than a-quartz--the stable polymorph of silica under ambient conditions. Previous studies have correlated these energetic metastabilities to molar volumes and framework densities. In this study, we consider the question of whether these
