Preparation of Monolithic Silica Aerogel of Low Thermal Conductivity by Ambient Pressure Drying

Author(s): Shih-Yuan Lu, Te-Yu Wei, Tso-Fu Chang, Yu-Cheng Chang

Monolithic silica aerogels were synthesized with very low thermal conductivity (0.036 W/mK) and high porosity (97%) via ambient pressure drying. This method of drying replaces supercritical drying which is more costly ...
