The reactions between water and mixed alkali glasses have been studied in the several temperatures and times ranging from a few to several houndred minutes. The effects of composition, SA/V ratios, and temperatures on the chemical durability were examined and the magnitude of the mixed-alkali effect was shown to be related to both the corrosion kinetics and the dominant mechanism of corrosion. If SA/V and temperature are higher, the mixed-alkali effect become large. Fro pH≥9, this effect also clearly appears. Because the leaching tendency of alkali and SiO₂are similar, the corrosion mechanism can be explained by ion-exchange and congruent leaching for SiO₂-rich nrotective laver.
