Description
In this study, we have investigated the influence of high-pressure on the structure of hydrous SiO2 glass by a combination of high-pressure Raman spectroscopy and X-ray Raman scattering (XRS) measurements. Previous data of anhydrous SiO2 glass serve as a reference. A detailed analysis of the SiO2 network of both compounds is provided. Moreover, we discuss the role of water in the glass structure of anhydrous SiO2. Our results imply that the water may play a key role in the melting processes.
