Abstract

The generation of ultrafine TiO, particles by the thermal decomposition of titanium tetraisopropoxide (TTIP) vapor was carried out experimentally using a well-controlled cylindrical furnace. The effects of the initial vapor concentration of the TTIP vapor, the reaction temperature, the temperature profile of the furnace and properties of seed particles on the particle size distribution of produced aerosol particles were examined to control the generation of particles. The observed trends agreed semiquantitatively with the simulation results obtained by solving the discrete-sectional aerosol dynamic equation accounting for Brownian coagulation and generation of monomer by chemical reaction.
