The silica alco-gel was obtained by the 2-step acid-base catalyzed TEOS. Aging in a solution of methyltrimethoxylsilane and trimethylating Si-OH groups increased the strength and stiffness of the wet gel by hexamethyldisilazane (HMDSA) on the surface of silica matrix. The modified silica aerogel was obtainted by CO2 supercritical drying method. The bulk densities of aerogels were between 30~100 mg/cm3. FTIR and some other experiment methods were used to investigate the structure and hydrophobic properties. The experiment results showed that the aerogel possessed perfect size-stability and hydrophobic properties. The aerogel micro-cylinder for ICF targets was manufactured by lathe machine.
