Title: Extended x-ray absorption fine structure determination of local structure in sol-gel-derived lead titanate, lead zirconate, and lead zirconate titanate

Abstract

We report extended x-ray absorption fine structure (EXAFS) measurements for partially heat-treated gels in the lead zirconate titanate system (PZT). Self-consistent results obtained from the titanium and zirconium {ital K}-edges and the lead {ital L}{sub III}-edge were used to determine bonding pathways between cations. For lead titanate (PT) and PZT gels, separate networks of predominantly Ti--O--Ti, Zr--O--Zr and Pb--O--Pb linkages were observed. For lead zirconate (PZ) gels, both Zr--O--Pb and Zr--O--Zr linkages were observed. The results indicate heterogeneity at the molecular level. These findings are discussed in terms of the evolution of structure for PZT materials prepared by our sol-gel method.
