Abstract: The hydrolysis-condensation process of Pb-Ti complex alkoxide has been studiedby turbidimetry.It was found that increase in both the amount of water and alkoxide concen-tration accelerated the hydrolysis-condensation reaction. NH4OH greatly promoted the hy-drolysis-condensation reaction,while HOAc showed a promotion effect at lower acid concen-tration,but a suppression effect at higher acid concentration.The results have been ex-plained in terms of hydrolysis-condensation reaction of alkoxide.

Key words: complex alkoxide, PbTiO3, hydrolysis-condensation reaction, turbidimetry
