Effect of. gamma. radiation on high-water-content glasses

Journal Article · · J. Am. Ceram. Soc.; (United States)
Na/sub 2/OX3SiO/sub 2/ glasses containing up to approx. =11 wt% water were prepared under high-pressure, hydrothermal conditions. The samples were exposed to gamma radiation of 5x10/sup 7/ rad. Optical and ESR measurements were made before and after exposure to radiation, and it was found that the induced absorption in the visible region decreased drastically with increasing H/sub 2/O concentration. The induced ESR signal-integrated intensity also decreased with increasing water content. After irradiation an increase was observed in the fundamental OH absorption bands in the IR region of the spectra of the water-containing specimens.
