Neutron and X-ray diffraction study on the hydrous SiO₂ glass up to 10 GPa

Abstract

We have conducted in-situ neutron and X-ray diffraction experiments on the hydrous silica glass at room temperature up to 10 GPa. Structure factors and radial distribution functions indicate that the intermediate range order of hydrous silica glass shrinks with increasing pressure, but the SiO₄ tetrahedra does not change up to 10 GPa.
