Chemisorbed Water Fundamental To Chemistry Of Glass Surfaces

Temperature-programmed static-SIMS has been shown to provide semi-quantitative analysis of water, hydroxide and hydroxyl on glass surfaces. In the case of pure silica glass, it can be quantitative, but for multicomponent glasses, more work is needed to speciate the various surface network-former hydroxyls from one another and from free metal hydroxides. This ability to quantitatively measure the surface hydroxyl species is necessary to provide a complete chemical characterization of any glass surface, and, in turn, to understand physical adsorption, fatigue and organic bonding at glass surfaces.
