Abstract
Ultrasonic spray pyrolysis of acetate-based precursors with precisely measured precursor drop size was employed to produce ZrO2 and CeO2 particles. A bimodal size distribution of the product particles indicates a significant influence of the gas-to-particle conversion mechanism in addition to the conventionally accepted one-particle-per-drop mechanism. Due to the differences in solubility of the precursors, ZrO2 particles are spherical in shape and smooth on their surfaces while the CeO2 particles are bowl-like in shape with uneven surfaces. Spherical and monodispersed particles with a peak diameter
