Abstract

The dielectric and piezoelectric properties for bismuth-based perovskite system (1-x) Bi (Ni23 Nb13) O3 -xPbTi O3 (BNN- PT100x) with x=0.6-0.95 were investigated. High-density polycrystalline ceramics were fabricated using a conventional solid-state reaction method. Morphotropic phase boundary (MPB) at x=0.625-0.65 composition was observed by x-ray-diffraction measurements, separating rhombohedral and tetragonal phases. Analogous to Pb (ZrTi) O3 ceramic, enhanced dielectric and piezoelectric activities were associated with the composition near the MPB. The dielectric constant (K33T) and piezoelectric coefficient (d33) for BNN-PT65 composition were found to be 1100 and 140 pCN, respectively, with a Curie temperature (Tc) around 273 °C. The addition of manganese (Mn) resulted in lowering the dielectric loss and increasing the mechanical quality factor Q when compared with the pure counterpart. The coercive field was found to increase to 30.7 kVcm when BNN-PT65 was modified with magnesium (Mg). These results demonstrate the BNN-PT system to be a competitive piezoelectric material with a reduced lead content.
