For the first time, an unambiguous characterization of a sol-gel precursor solution for lead zirconate titanate (PZT) ceramics was carried out. A new lead-zirconium oxoacetatoalkoxide [PbZr[sub 2](O)(OAc)[sub 2](OEt)[sub 6]][sub 2] was crystallized from an ethanol solution of Pb(OAc)[sub 2], Zr(OEt)[sub 4], and Ti(OEt)[sub 4]. In this compound the Zr cations have a heptacoordination geometry instead of the hexacoordination as in the perovskite oxide phase. The chemical heterogeneity in solution may have an important effect on the evolution of phase development during the crystallization of sol-gel derived PZT. 24 refs., 2 figs.
