Keywords: flame spray pyrolysis, nanoparticles, synthesis

Iron-oxide nanoparticles have been synthesized via liquid-fed flame spray pyrolysis (FSP) under variable pressure conditions. The work focuses on the effect of pressure, precursor flow rate, and flame stoichiometry on particle size, composition, and morphology. The particle properties are investigated by nitrogen adsorption (BET), transmission electron microscopy (TEM), and X ray diffraction (XRD). The experimental investigations are supported by numerical simulations. Spray formation and droplet evaporation are modeled in an Euler-Lagrange framework and turbulent spray combustion is simulated using simplified reaction kinetics. The population balance equations for the particle dynamics are solved, assuming a mono-disperse distribution of the particle size.
