TLDR
In this article, the hydration of soda-lime glass is studied using resonant nuclear reactions to measure the hydrogen and sodium profiles of hydrated glasses, and the measured hydration profiles are discussed in relationship to the Doremus model of interdiffusing ions.Abstract:
The hydration of soda-lime glass is studied using resonant nuclear reactions to measure the hydrogen and sodium profiles of hydrated glasses. The rate of growth of the surface layer of hydrated glass is initially proportional to the square root of time as is characteristic of diffusion controlled processes. After longer exposure a steady-state hydration profile is observed, which indicates that in addition to the diffusion controlled reaction there is a slow etching of the glass surface. The measured hydration profiles are discussed in relationship to the Doremus model of interdiffusing ions, which is found to be in good agreement with the data. This model is also discussed in relationship to measured hydration profiles of vacuum heated samples of hydrated glass.read more

Diffusion of water in rhyolitic glasses.
TL;DR: The activation energy for diffusion in rhyolitic glasses is well correlated with neutral species radii of He, Ne, H2O, and Ar, and supports the contention that the diffusing species for "water" is neutral molecular H 2O.

Unifying natural and laboratory chemical weathering with interfacial dissolution–reprecipitation: A study based on the nanometer-scale chemistry of fluid–silicate interfaces
Roland Hellmann,Richard Wirth,Damien Daval,Jean-Paul Barnes,J.M. Penisson,Delphine Tisserand,Thierry Epicier,Brigitte Florin,Richard L. Hervig +8 more
TL;DR: In this article, the authors used high resolution and energy filtered transmission electron microscopy (HRTEM, EFTEM) to study mineral-fluid interfaces using TEM foils cut directly across the reaction boundaries, which allowed measurements to be made directly in cross section at nanometer to sub-nanometer resolution.

Origin and consequences of silicate glass passivation by surface layers
Stéphane Gin,Patrick Jollivet,Maxime Fournier,Frédéric Angeli,Pierre Frugier,Thibault Charpentier +5 more
TL;DR: The low corrosion rate resulting from the formation of this stable passivating layer enables the objective of durability to be met, while progress in the fundamental understanding of corrosion unlocks the potential for optimizing the design of nuclear glass-geological disposal.

First-order dissolution rate law and the role of surface layers in glass performance assessment
Bernd Grambow,R. Müller +1 more
TL;DR: In this paper, the role of the surface layer in the first-order dissolution rate law was discussed and two alternative ways by which the protective layer concept can be coupled to the saturation concept were proposed.

An EFTEM/HRTEM high-resolution study of the near surface of labradorite feldspar altered at acid pH: evidence for interfacial dissolution-reprecipitation
TL;DR: In this article, an approach combining high-resolution and energy-filtered transmission electron microscopy (HRTEM and EFTEM) was used to study the interfacial region that delimits the near-surface altered zone and non-altered labradorite feldspar after dissolution under acid pH conditions.

New precision technique for measuring the concentration versus depth of hydrogen in solids
TL;DR: In this paper, a method for the measurement of the concentration of hydrogen versus depth in solids using the 1H+15N resonant nuclear reaction is discussed, which has a typical depth resolution of 50-100 A, can be used to a depth of several microns, and can measure hydrogen in concentrations of one part per thousand or greater.

Hydration rate of obsidian.
Irving Friedman,William D. Long +1 more
TL;DR: The hydration rates of 12 obsidian samples of different chemical compositions were measured and an expression relating hydration rate to temperature was derived, and the results show that weather records can give a good approximation to the true EHT, particularly in tropical and subtropical climates.
