Glass-Water Interactions for Long-Term Durability

This session will focus on the unique application of glasses and glass-ceramics resistant to dissolution and degradation in aqueous environments. This includes borosilicate glass, phosphate glass, and glass-ceramic materials developed for nuclear waste confinement. Studies using natural and man-made glasses to challenge long-term issues of aqueous degradation, such as natural glasses, archeological glasses and other simple model glasses are also of interest. Elucidation of the mechanisms and kinetics of glass degradation in studies conducted under various conditions are welcomed, for example those which investigate the influence of solution composition, temperature, glass composition, reactive surface area, gel layers, secondary phases, environmental materials, radiation, water vapor/liquid water, etc., on dissolution.

We also encourage discussion of studies that develop models capable of describing one or more of the advanced stages of glass corrosion (rate drop, residual rate, resumption of alteration), and those which investigate the influence of degradation on material performance.
