Abstract:

The surface of ion irradiated alkali silicate glasses is sensitized to chemical attack by atmospheric water vapour. After initial evolution of hydrogen, this attack leads to the slow conversion of certain regions on the glass surface to water soluble corrosion products. The observations suggest that the regions involved in this conversion are particles of a second phase, distributed throughout the main matrix, and they point to the importance of phase separation in determining the stability of glasses under irradiation.
