## Abstract About โˆผ2.1 ร— 10^โˆ’3^ mol SiO~2~ cm^โˆ’3^ and โˆผ88%โ€volume liquidโ€phase silica wet gels were prepared from oxalicโ€acidโ€catalyzed tetraethoxysilane (TEOS) sonohydrolysis. Aerogels were obtained by supercritical CO~2~ extraction. The samples were analyzed by thermogravimetry, smallโ€angle Xโ€ray
