Abstract

Diffusion of water in silica glass was studied under high pressure and water fugacities. To clarify the role of each parameter, experiments were conducted by varying the pressure at constant fugacity and by varying the fugacity at constant pressure. Concentrations of diffusing substances were obtained using FTIR spectroscopy. The solubility of molecular water species was observed to decrease with pressure while it increased linearly with fugacity. The diffusivities of hydroxyl and molecular water species were obtained at different pressures and fugacities.
