测定了康宁015钠钙硅酸盐玻璃在水、盐溶液中不同温度下的pH随处理时间的变化规律。pH值先增大到最大值，然后减小。这种pH变化是由一系列化学反应引起的，并讨论了产生的速率常数。水合层的红外吸收主要来自于SiOH基团、分子吸附的水和氢键。反应速率在盐溶液中比在水中高。
The pH of Corning 015 soda-lime silicate glass was measured in water and salt solutions at different temperatures as a function of treatment time. The pH increased to a maximum and then decreased. This pH change was modeled as resulting from a sequence of chemical reactions, and the resulting rate constants discussed. The infrared absorption of the hydrated layers showed contributions from SiOH groups, molecularly adsorbed water and hydrogen bonding. Reaction rates were higher in salt solutions than in water.
