abstract = "The formation and growth of polymeric particles during the hydrolysis and condensation of PbZr0.3Ti0.7O3 (PZT 30/70) precursor solutions have been studied as functions of time by using photon correlation spectroscopy (PCS). Particle shape was deduced by measuring the rheological properties of the sols and was found to remain chain-like during sol ageing. Various factors that affect the ageing of PZT sols have been investigated. Ethylene glycol (EG) was found to greatly accelerate the hydrolysis and condensation of the acid-modified Pb-free Zr/Ti solutions but had little effect on the particle growth for the Pb-containing PZT sols. Temperature and H2O concentration were found to have major effects on the ageing behaviors. The higher the temperature and H2O concentration, the higher the particle growth rates and the faster the sol gels.",
