Abstract: The grain growth and kinetics of nanocrystalline titania prepared by using a precursor methodfrom titanium terachloride were studied. The grain size grew slowly when annealing temperaturebelow 773K but fast above 773K. The grain growth activation energy is 54.62±3.73kJ/mol at T >773K and 6.43±3.39kJ/mol at T <773K.

Key words: titania, grain growth, kinetics, activation energy
