Summary

A sodium alumino-silicate (NAS) Corning glass (code#0317) was chosen for this investigation. The glass was surface modified using a slurry ion-exchange. The interdiffusion of K+ for Na+ was carried out in the presence of a microwave electric field at 2.45 GHz. Similar chemical/heat treatments were carried out in a conventional furnace for the sake of comparison. Electron microprobe (EMP) was used to derive the concentration profile of potassium after ion-exchange. The diffusion coefficients were calculated for both heating methods. The dielectric properties of the ion-exchange slurry and those of the glass matrix were evaluated over a wide range of temperatures by the frequency shift method.
