Effect of water incorporation on the diffusion of sodium in Type I silica glass

The diffusion of sodium ions in Type I silica glass was studied experimentally by using Na-22 as a radioactive tracer at temperatures between 400°C and 700°C. It was found that the sodium tracer diffusion coefficient in as-received glass was well described by an Arrhenius equation. All residual radi...
