Abstract

Using the ultrasonic pyrolysis method, spherical SiO₂ powders were synthesized from aqueous SiO₂ sol as a starting material. The effects of pyrolysis conditions such as reaction temperature, SiO₂ sol concentration, and physical properties of precursor were investigated for the morphologies of the resulting SiO₂ powders. The particle size, shape, and crystallite size of the synthesized SiO₂ powders were demonstrated according to the pyrolysis conditions. Generally, the synthesized SiO₂ particles were amorphous phase and showed spherical morphology with a smooth surface. It was revealed that increased crystallite size and decreased spherical SiO₂ particle size were obtained with increases of the pyrolysis reaction temperature. Also, quantity of spherical SiO₂ particles decreased with the decrease in the concentration and surface tension of the precursor.
