Abstract: Nanosized anatase TiO2 powder was prepared by the high-temperature hydrolysis of titaniumtetrabutoalde and crystallization in the organic media. The nanosized powder was charasterizationby XRD, BET, TEM, TG and DTA methods. The powder remains anatase crystallites in awide temperature range (200-700℃). The average diameter of the nanosized TiO2 powder aftercalcination at 550 C is 14urn and the specific surface is >100m2/g.

Key words: titanium dioalde, nanosized powder, organic media, preparation and characterization
