Abstract

Two different lead ion positions with tetragonal and orthorhombic localsymmetry were revealed in PbZrO3 ceramics on the base of 207Pb NMRspectra measurements at room temperature. The obtained data and theiranalysis on the base of the spectra shape calculations are in agreement witha symmetry of Pbam nonpolar group space of PbZrO3. The comparison ofobserved spectra in PbTiO3 and PbZrO3 with calculated spectra allowingfor resonance frequency chemical shift and spin-spin interaction show that the displacements of lead and oxygen ions are not random quantities inthe investigated PbZrO3 ceramic samples.
