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.
