Abstract

Post-indentation slow crack growth in soda-lime-silica glass in various aqueous solutions was investigated. Measurements of crack length and streaming potential at the glass/solution interface were carried out in order to understand the mechanism of slow crack growth of glass. The crack growth depended on the pH of electrolyte, and was enhanced by the change of pH from 1 to 10. This behavior was in good agreement with the prediction obtained from the charged state at the interface. These results were discussed in terms of the charged state at glass/solution interface and its effect on the stress corrosion reaction in electrolytes.
