The drying process of wet silica gels obtained from TEOS has been studied by means of FT-IR, DSC and specific surface area measurements. FT-IR spectroscopic results have not given any important information about the drying process of silica gels. However, DSC results have shown a dependence of the DSC peak area on drying time. Three different water/alkoxide ratio were studied, and the DSC peak...
