Highly porous and hydrophobic silica aerogel is fabricated using fly ash and trona ore as the starting materials and the cost-effective ambient pressure drying technique. The optimal calcination parameters are determined as temperature of 850°C, holding time of 2h, and the trona ore/fly ash mass ratio of 1.4. The CO2 release mechanism during calcination is proposed and has been verified by the Thermogravimetric...
Silica aerogel has been formed using CO2 gas as the gelation agent through the low-cost ambient pressure drying technique. With water wash and the following solvent exchange process for Na+ removal, this synthesis route has no ion exchange resin used and becomes more straightforward. In order to reduce the silica particle and pore sizes, different hydrolysis-condensation rate control agents including...
