Title

Sodium Diffusion in High-Silica Glass

Abstract

Isotope effect and electrical conductivity measurements were used to investigate the mechanism of Na+ diffusion in high-SiO2 glass. A Haven ratio near unity and comparatively high isotope effect values suggest a quasi-interstitial mechanism for Na+ diffusion. At low Na+ concentration the Na+−Na+ separation distance is so large that the Na+ jumps become uncorrelated.
