Resently,the studies of silica aerogels have been more and more extensive.Used as the lightest solid material,silica aerogels have many unique properties and the best property in thermal insulation. But the key of studying is the preparation con-ditions. In this paper,the orthogonal experiment had been designed by using four factors and three levels to study their optimal preparation conditions at ambient pressure,and the influences of the four factors TEOS,water,ethanol,pH values to silica aerogels properties had also been studied. The results showed that the sample prepared at the conditions of TEOS:H2O:EtOH=1: 6:5(mol ratio)pH=6~7 and the temperature of 70℃ under the water bathing had better properties.
