Abstract	Titania thin films were prepared by using aerosol flame deposition process via the pyrolysis of titanium tetra-isopropoxide (TTIP) precursor. We analyzed the specific surface area, primary and secondary particle sizes, crystal structure, thin film morphology and thickness by BET method, electrophoretic light scattering, X-ray diffraction and scanning electron microscopy, respectively. The specific surface area of TiO$_{2}$ particles deposited is over three-times larger than that of commercial Degussa P25. Crystallite structure of TiO$_{2}$ particles can be controlled by changing the ratio of CH$_{4}$/O$_{2}$ flow rates. We could prepare TiO$_{2}$ thin films with single anatase phase by keeping the ratio of CH$_{4}$/O$_{2}$ flow rates at 200 ml/min: 1,000ml/min. As N$_{2}$ carrier gas flow rate to bubbler increases, the primary and secondary particle sizes increase, but decrease with increasing total N$_{2}$ gas flow rate through the central tube. The shorter the deposition height is, the smaller the deposition area is, but the thin film becomes thicker in the central region.
