| Abstract |
Currently there are several models discussed to describe the formation of monodispersed
silica particles. Monodisperse colloidal silica was prepared from tetraethoxysilane in mixture of
ammonia, water and ethanol. Chemical system reaction permits the controlled growth of silica
nanoparticles and subsequent condition of silicic acid in alcoholic solution. The molar ratio of
NH4OH, C2H5OH and H2O has a significant effect on particle size and specific surface area of silica
particles. The nature of particles was evaluated using X-ray diffraction, energy dispersive
spectroscopy (EDS) and BET. The morphology of particles were determined by scanning electron
microscopy (SEM) and transmission electron microscopy(TEM). |
