AB - The spherical SiO2 powders were synthesized by the scaled-up ultrasonic pyrolysis (USP). The aqueous SiO2 sol, which contained 20~30 nm SiO2 particles, was used as a precursor for the scaled-up USP. The effects of the USP operating conditions and precursor conditions were systematically investigated, including reaction temperature, gas flow rate, and the concentration of SiO2 sol on the morphologies of synthesized SiO2 particles. the synthesized SiO2 particle showed a pseudo-crystal phase, spherical morphology, and a smooth surface. The size of the spherical SiO2 particle decreased as both reaction temperature increased and precursor concentration decreased. In addition, the synthesized SiO2 particle size was increased by increasing the gas flow rate. Lastly, the scaled-up USP was compared with the lab-scale USP based on the same process conditions. Due to a short retention time in the reaction tube during the USP process, the SiO2 particle synthesized via the lab-scale USP showed a larger particle size.
