Oxygen Self-diffusion Coefficient for Li₂O⋅2 SiO₂ Glass

Abstract

Oxygen self-diffusion coefficient has been studied in Li₂O⋅2 SiO₂ glass. The concentration distribution of stable ¹⁸O isotope within the glass after the gas/solid exchange was determined by secondary ion mass spectrometry. A diffusion coefficient and a surface exchange reaction coefficient were determined from the concentration distribution.
