Diffusion of strontium ion in silver chloride

Journal of Physics and Chemistry of Solids, 1969
Abstract The activation energy for diffusion of Sr 2 in AgCl has been found to be 0-98 eV, by means of a standard sectioning technique. The results are consistent with a vacancy mechanism and corroborate the hypothesis that ions with no outer d -shell electrons diffuse almost entirely substitutionally in silver halides.

Models for Chloride Ion Diffusion in Archaeological Iron

Studies in Conservation, 2001
La vitesse a laquelle les ions chlorure diffusent du fer archeologique a une solution de traitement depend de la facon dont ces ions sont distribues initialement dans les couches de corrosion. Cet article compare les solutions de l'equation de diffusion pour deux cas limites: (1) lorsque les ions chlorure sont repartis initialement de facon uniforme ...

Diffusion mechanism of chloride ions in sodium montmorillonite

Journal of Contaminant Hydrology, 2001
For safety assessment of geological disposal of HLW, it is necessary to understand the diffusion mechanism of radionuclides in compacted bentonite. In this study, the diffusion behavior of chloride ions in compacted montmorillonite was studied from the viewpoints of the activation energy for apparent diffusion and the basal spacing of the compacted ...

Diffusion behavior of chloride ions in concrete

Cement and Concrete Research, 1996
In the present paper, an analysis of the diffusion behavior of chloride ions in concrete is presented. In concentrated electrolytic aqueous solutions such as seawater or that typically used in laboratory experiments, the effect of ionic interaction may significantly reduce the chemical potential and thus the driving force of the diffusing species ...
