Opal, cristobalite, and tridymite: Noncrystallinity versus crystallinity, nomenclature of the silica minerals and bibliography
TL;DR: A classification and nomenclature for these forms is discussed in this article, where the authors provide an extensive bibliography of the literature on tridymite, cristobalite, and opal, as well as opal-C. The TEM evidence showing domains in the range 10-30 nm in a matrix of disordered opal suggest that the proper term for this system is paracrystalline analogous to inorganic and organic polymers.

TL;DR: In this article, the authors investigated the influence of extreme temperatures (from 25° to 1000°C) followed by two cooling methods (both rapid and slow) on the mechanical behaviour of clay-rich Hawkesbury sandstone under uniaxial conditions.

H-Bond Features of Fully Hydroxylated Surfaces of Crystalline Silica Polymorphs: A Periodic B3LYP Study
TL;DR: In this paper, different models of hydroxylated surfaces of quartz, cristobalite, and tridymite have been studied with the hybrid B3LYP functional using the Gaussian basis set of polarized double-ζ quality with periodic boundary conditions.

Role of germanium in the formation of double four rings in zeolites
TL;DR: In this article, plane wave density functional theory calculations are used to characterize and rationalize the site preferences, energies, and structural changes occurring when Ge is gradually substituted into the BEC framework up to 25% loadings.

The Polymorphism of Silicon Dioxide and the Structure of Tridymite
TL;DR: A survey of the internal structures of the materials can be found in this paper, where the authors take into account the industries in which the material is of primary importance, e.g., glass, clay, etc., and the various purposes to which silica in one form or another is applied.
