Time-resolved small angle X-ray scattering study of sol-gel precursor solutions of lead zirconate titanate and zirconia

► Evolution of nanostructure in PZT and zirconia sols studied by SAXS. ► Similar cylindrical structural motifs observed in PZT and zirconia sols. ► Cylindrical motifs are probably stacked zirconia-based tetramers. ► No scattering contributions from Pb and Ti observed in PZT sols.
