Recent years have been witness to advances in our understanding of the high-pressure behavior of crystalline and amorphous silica. Experimental developments made possible by new diffraction techniques have generated new findings to megabar pressures (i.e., above 100 GPa). Theoretical advances, including increasingly accurate first-principles methods and interatomic potentials such as those first proposed by Yoshito Matsui and co-workers, have provided predictions and new understanding of experimental data. We review these theoretical developments in the context of recent experimental findings. Our analyses provides a basis for understanding the extensive metastablity of high-pressure crystalline structures, the nature of the short- and intermediate-range order of the high-pressure amorphous material, and both equilibrium and nonequilibrium transformations. Such study also provides insight into the structural basis of anomalous transport properties of the liquid predicted at high pressure.
The nature of silica under pressure is a textbook example of the intersection of condensed-matter physics and mineralogy . Silica is of obvious importance in mineralogy, as SiO2 is abundant in the Earth's crust and plays a major role in the deep interior, both as a product of chemical reactions and as an important secondary phase. From the point of view of condensed-matter physics, SiO2 presents an important system for investigating pressure-induced polymorphism, providing examples of first-order reconstructive transitions , displacive (soft-mode-driven) transitions , pressure-induced amorphization [4, 5], and polymorphism and polyamorphism [4–6]. Silica is also of great technological interest in both its crystalline and glassy forms.
