Abstract Lead zirconate (PZ) materials were prepared by a sol-gel process in a non-flowing air atmosphere with no continuous agitation using lead acetate and zirconium propoxide in methoxyethanol as the precursor materials. Fourier transform infrared and Raman spectroscopy were used to characterize the structural changes that occurred during various stages of this preparation. Crystalline phase formation differences were noted during this sol-gel preparation for PZ in comparison to those occurring during the related preparation for lead titanate (PT). Metallic lead and lead oxide (PbO) were formed during the heating steps of this process in an air atmosphere for PZ.In situ Raman spectra were also measured at higher temperatures for the resulting sol-gel prepared PbZrO3 material in order to investigate its phase-transition and soft-mode behaviour.
