Abstract

Lead Zirconate titanate [PbZr0.52Ti0.48O3] (PZT) material was synthesized by the ceramic route. The morphology of PbZr0.52Ti0.48O3 sample was observed by scanning electron microscopy and its shows large grain sizes in the range of 1-4 μm. The higher dc resistivity 1.146 x105 (Ω.cm) was observed for PZT sample at room temperature. Temperature-dependent P-E loop measurements of PZT sample were recorded by the P-E tracer circuit. The values of remnant polarization (4.53, 2.23 and 1.28 μC/cm2) and saturation polarization (5.60, 4.93 and 3.19 μC/cm2) were observed at 100°C, 150 °C and 200°C respectively. The obtained coercivity values (5.14, 5.88 and 6.80 kV/cm) from the temperature-dependent P-E loops were found to be increased with an increase in the temperature. The values of dielectric constant were found between 2646 and 417 (F/cm) for PZT sample when it was exposed to the frequency of applied field varies from log (1.2) to log (6.0). The variation in loss tangent was recorded between 0.73 and 0.10 at log (3.925) and log (2.388) Hz, respectively. The frequency-dependent conductivity of PZT material was recorded at room temperature. Such types of PZT materials show good thermal stability and therefore, it can be used for high-temperature piezoelectric applications.
