Preparation and Characterization of Ultralow Density Silica Aerogels by Acetonitrile Supercritical Drying
Author(s): Bin Zhou, Guang Wu Liu, Qiu Jie Yu, Xing Yuan Ni
Ultralow density silica aerogels were formulated by sol-gel process using tetramethyl orthosilicate as the precursor. A supercritical drying step was performed using acetonitrile solvent extraction. These aerogels were found to ...
