摘要：

Silica alcogels prepared from tetramethylorthosilicate were supercritically dried with methanol, ethanol, 2-propanol and carbon dioxide media. The density, transmittance, specific surface area and pore size of the aerogels obtained were compared. The supercritical drying media affects the properties of the aerogel.
