Abstract

This article aims to prepare high quality of TiO2 powder and study the effect of annealing temperature. TiO2 particles were synthesized by sol-gel method using titanium tetra chloride (TiCl4) as a precursor. The dried gel was annealed at temperatures of 500oC, 600oC, 700°C and 800 °C each for 4 hours. The as-prepared samples were further characterized using X-Ray diffraction (XRD), Scanning electron microscope (SEM), Energy dispersive X-ray Fluorescence spectrometer (EDX), XRD showed anatase structure after annealing and its diffraction scattering intensity indicated the improvement in the crystal structure quality of TiO2 as the temperature increases. SEM micrographs showed a randomly distributed and non-uniform cluster of TiO2 that has a size increase with annealing temperatures. EDX indicated stoichiometric chemical composition between Ti and O enhanced by annealing.
