Abstract

In this paper, the microstructural characteristics of ternary ceramic powders Al2O3-SiO2- ZNO system prepared by SOL-GEL method, in order to increase surface area of ZNO nanocrystals supported on silica-alumina matrix, have been studied. Values of 20, 50 and 70 weight percents of zinc oxide with an equal weight ratio of SiO2-Al2O3, using simultaneous reaction of zinc nitrate (Zn (NO3)2.6H2O), tetraethyl orthosilicate, (TEOS) and aluminum nitrate (Al (NO3)3.9H2O) were synthesized. The nanostructure of prepared COMPOSITEs were characterized by X-ray diffraction, SEM/EDS and BET studies. The results showed that crystaline phase zinc oxide has been formed in amorphous silica-alumina matrix, which led to reducing zinc oxide particles size, preventing of agglomeration and increasing specific surface.
