Sodium-hydrogen interdiffusion in sodium silicate glasses

TLDR
In this article, the authors used sputter-induced photon spectrometry technique (SIPS) to measure the depth profiles of hydrogen and sodium in Na2O · 3 SiO2 glasses and determined the thickness of the hydrated layers as functions of time and temperature.
Abstract
The hydration of Na2O · 3 SiO2 glasses is studied using the sputter-induced photon spectrometry technique (SIPS) to measure the depth-profiles of hydrogen and sodium. The results clearly show a penetration of hydrogen and a leaching of sodium in the glass. The thicknesses of the hydrated layers are determined as functions of time and temperature. The thicknes dependence on the square root of time indicates that a diffusion process is in operation. The data are fitted to he Doremus model of interdiffusing ions and the diffusion coefficients for hydrogen and sodium are calculated.

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.

Chemical durability of glasses

TL;DR: In this article, it is shown that during leaching the structure of the glass is changed and the moving particles are altered, which means that some fundamentals for applying the usual diffusion equations are not valid.

Characterization of glass corrosion and durability

TL;DR: In this paper, the surface and bulk structural state of a glass object is described in terms of intrinsic structural features, i.e., the structural changes in the bulk or surface structure of the glass due to processing or environmental conditions.
