- •
Stress Corrosion Cracking (SCC) response of sodium borosilicate glasses as a function of their chemical composition.
- •
Increasing the sodium concentration causes the glasses environmental limit (Ke) to shift to higher values.
- •
When [Na2O] exceeds a critical value, Na+ ions act as network modifiers on the Si and B networks affecting SCC in Region I.
- •
Above this critical value, increasing [Na2O] causes depolymerization increasing in the slope in Region I.
