Glass Corrosion.
Abstract
An approach is developed for understanding formation of gel films on glass surfaces during water exposure. Compositional and microstructural data from ir reflection spectroscopy, scanning electron microscopy, and electron microprobe analysis are used with parameters defined from solution-analysis data to produce a SiO2 composition profile of the corroded surface. This model profile is compared with a measured profile and used to interpret differences in corrosion resistance of binary Li2O- and Na2O-SiO2 glasses. Effects of corrosion temperature, water flow rate, cell volume, relative humidity, pH, type of acid, residual glassy phase in a glass-ceramic, and surface roughness on film formation and stability are evaluated. The theoretical and experimental basis for using infrared reflection spectroscopy as a quantitative method for glass structural analysis is described and applied to binary alkali-silicate and lead germanate glasses. X-ray amorphous scattering of a K2O-SiO2 glass confirms the development of a vitreous silica-like structure to the surface film. Characterization methods for glass are reviewed. (Author)
