Abstract: Thermal expansion properties have been measured for the ceramic lead zirconate titanate-lead zinc niobate [(1-x)PZT-(x)PZN] in the temperature range of -100 to +450 °C. For all ceramics examined, the deviations from the straight line below Burns temperature were observed. The dynamic polarization fluctuations in their relaxor compositions are believed to play a role in this deviation. Burns temperature was determined and the local polarization (Pd) was calculated from the thermal expansion data. Various aspects of understanding the polarization behavior and other effects in this ferroelectric system were examined and discussed. © Springer Science+Business Media, LLC 2012.
