Paper Abstract

Lead zirconate titanate, Pb(ZrTi)03 (PZT), a solid-solution of ferroelectric PbTiO3 (Tc=490°C) and antiferroelectric PbZrO3 (Tc=230°C), with varying Zr/Ti ratios has wide industrial applications. The variation of Zr/Ti ratio and the suitable substitutions at A/ or B sites influence the physical properties and/or device parameters of PZT to a great extent. The La modified PZT (PLZT) of different Zr/Ti ratios and La concentrations has been studied extensively using various methods. It is therefore interesting to explore the possibilities of fine-tuning the characteristics of PLZT (8:60:40) with the help of an additional dopant at the La site. Here we report our work on synthesis and characterization of La, Bi ions doped PZT piezo ceramics.
