Abstract

Glasses with the same composition and hydroxyl contents were prepared by conventional melting and by hydrolysis of alkoxides. The differential scanning calorimeter (DSC) was used to compare the kinetics of structural relaxation of the glasses. Detailed examination of the data shows that there is no difference between them after the gel has been sintered near the glass transition temperature. Changing the oxide content of the melted glass causes significant changes in the DSC plots, so it is very important to confirm (as was done in this study) that the gel and melted glasses are identical in composition.
