Abstract: In this study, the applicability of the flame spray pyrolysis (FSP) method in the production of alpha-Al2O3 based TiO2 coatings was investigated. Plate-like alpha-Al2O3 particles, with a particle size of 8-30 mu m, were dispersed in a solution of titanium tetraisopropoxide-xylene, a low solids suspension was prepared, and then a TiO2 coating was obtained on alpha-Al2O3 platelets by feeding the precursor suspension into a pre-mixed methane/oxygen flame in a FSP reactor. Obtained coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX) methods. While the presence of heterogeneous nucleated TiO2 coating on alpha-Al2O3 platelet surfaces was revealed by the characterization process performed, it was also observed that homogeneously nucleated TiO2 nanoparticles were obtained during the process.
