Abstract Nanocrystalline titania particles were prepared by using precursor method from titanium tetrachloride.The microstructure was determined by using DTA-TG,XRD,TEM and Q-900 analyses.The results show that the spherical nanocrystal with rutile structure has an avarage diameter of 8.5 nm,good dispersity and purity.It's size distribution is from 5.0 nm to 15.0 nm.

Key words: TiO_2 nanocrystal precursor method
