The local environment of Zr atoms in amorphous precursors and intermediate products of the thermal treatment leading to perovskite PbZrO3 ceramic materials is studied by EXAFS. The coordination of Zr depends significantly on the choice of the starting Zr alkoxide. The Zr-O-Zr bond in an amorphous phase persists till the final stage of heating at 800 °C.
