by sol-gel method and to characterize the synthesized silica nanostructures. Silica nanoparticles were synthesized
via the sol-gel method using Tetraethyl orthosilicate as a precursor. The acetic acid and distilled water were used as
the catalyst and the hydrolyzing agent. Varied parameters of the study were the aging time in the range of 2 to 6 h
and the calcination temperature in the range of 600–700 ◦C. The obtained silica nanopowder was characterized
using FESEM, and Nano-Particle Size Analyzer. The results show that the silica nanospheres were successfully
synthesized by using sol-gel method with the optimum parameters of 700 ◦C of calcination temperature and 2 h of
aging time. The average size of silica nanoparticles was in the range of 79.68 nm to 87.35 nm.
