Abstract
The synthesis of alumina aerogels has been carried out by hydrolysis of alu minium isopropylate as an aerogel precursor dissolved in isopropanol or met hanol, followed by gelation of the sob obtained and drying under supercriti cal conditions and calcination. The influence of two main preparation param eters, precursor concentration and reagents (water to aluminium isopropylat e) mole ratio, on the physicochemical properties of aerogels was investigat ed.
