Synthesis and Characterization of PbZrTiO3 Ceramics

Lead zirconate titanate (PZT) ceramic powders were prepared via conventional solid-state reaction method. The prepared samples were sintered at 900oC for 2 h. The sintered materials were characterized for structural analysis. The diffraction pattern reveals the pure phase formation of perovskite PZT structure. The morphology is analyzed by scanning electron microscope and average grain size is evaluated to be of 3.3 μm. The frequency and temperature dependence of electrical properties such as dielectric constant and dielectric loss was studied using LCR controller. In addition, the ferroelectric behavior was investigated by P-E loop tracer.
