Nanosized amorphous TiO2 powders with a specific surface area of 501 m2.g-1 were prepared by hydrolysis. Aftercalcined at 400℃ for 2 h, the prepared amorphous TiO2 powders were fully transformed into anatase crystallitesthe samples of nanosized amorphous TiO2 mixed with microsized anatase, nanosized anatase, or nanosized α-Al2O3respectively. Effects of sample packing, anatase addition, or α-Al2O3 addition on the crystallization behavior ofnanosized amorphous TiO2 were analyzed.
