摘要：
A chemical reactor is designed and developed to synthesize silica nano-powders by oxidation of tetraethyl orthosilicate (TEOS) using a three-port diffusion flame burner. Nano-silica powders were successfully synthesized. The particle size of the silica powders were confirmed by AFM and TEM techniques. Scanning electron microscopy (SEM) reveals that as-synthesized silica powders are in agglomerated condition. Phase analysis using XRD shows that the nano-silica in as-prepared condition is in amorphous form. However, during subsequent heat-treatment, it becomes crystalline.
