Preparation and Caractarization Of Silica Aerogel By Using Sol-gel method


Abstract in English

During this study, various types of silicon oxide were prepared as aerogel and xerogel using multiple precursors and different drying technics. Some of these samples were prepared from Sodium silicate (waterglass) Na2SiO3 as a precursor which is a cheap material, while others were prepared using tetraethoxysilane (TEOS).
