The clear and transparent sols of BaTi acetate were prepared from tetrabutyltitanate, barium acetate aqueous solution, ethanol and acetic acid. The BaTi acetate sols were transferred into gels by sol-gel process, and the gels were dried and calcined to nanostructured BaTiO₃ powders. The sol-gel transition process has been investigated as functions of initial pH value of sol, time and temperature of gel for the tetrabutyltitanate-barium acetate-acetic acid system. The rheological behavior occurred in the sol-gel transition have been investigated. It is found that the initial pH value of the sol affected not only the sol-gel transition, but also the particle size of the final calcined BaTiO₃ powders. For the BaTi acetate sols with initial pH values of 3.8 and 5.3, the time from sol to gel was 40 and 120 h at 20℃, respectively; after dried at 80℃ and calcined at 700℃, the grain size of BaTiO₃ powders was 90 and 70 nm, respectively.
