  • Sol-gel synthesis and characterization of silica, aluminia, titania and their mixed oxide aerogels
    Novak, Zoran ...
    The preparation and characterization of aerogels metal oxides (SiO2, Al2O3,TiO2), binary mixed oxides (SiO2-Al2O3 and SiO2-TiO2), and various NiO aerogels (NiO-Al2O3, NiO-SiO2 and NiO-SiO2-Al2O3) is ... presented. The preparation of aerogels includes several steps: sol-gel synthesis, drying and,finally, thermal treatment. Excellent properties of aerogels, obtained with the sol-gel synthesis, were preserved with supercritical drying with Co2.Due to this fact, supercritical drying out at the conditions above binarycritical curve of the sovent-Co2, where the solvent and Co2 are completely miscible. All produced aerogels were characterizied by means of nitrogen physisorption at 77K, single point BET surface area measurements (adsorption of argon-nitrogen gas mixture), X-ray diffraction and thermal analyses.
