Preparation and Characterization of Ultralow Density Silica Aerogels by Acetonitrile Supercritical Drying

Author(s): , , ,

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 ...
