영문 초록

The spherical particles of CeO_2/SiO_2 composite powder with narrow-size distribution and pure phase particles were synthesized by ultrasonic spray pyrolysis method from aqueous cerium sulfate solution. The resulting composite powder was characterized by X-ray diffraction, scanning electron microscopy, transmittance electron microscopy, in-vitro sun protect factor, and BET surface area analysis. The concentration of cerium sulfate was tested to vary the particle size from 3.40{times}10^{-3} to 1.02{times}10^{-2}mol/cm^3 to study concentration effect of starting material. The average particle size from the 3.40{times}10^{-3}mol/cm^3 concentration was found to be slightly smaller than that from the 1.02{times}10^{-2}mol/cm^3 concentration, because of the relation between the droplet size and the concentration of the starting material solution
