Extending the investigations on Bi-based solid solution for lead-free piezoelectric ceramics, this paper consider the complex solid-solution system (1-x)(Bi0.5Na0.5)TiO3-xBa(Zr0.04Ti0.96)O3 [(1-x)BNT-xBZT] for x < 0.12. High density polycrystalline ceramics were fabricated using conventional solid-state processing methods. These ceramics are then taken for structure and properties measurements.

Although PbZrO3-PbTiO3 (PZT)-based ceramics are playing a dominant role in piezoelectric materials, their evaporation of harmful lead oxide during the sintering process causes a crucial environment problem. It is necessary to search for lead-free piezoelectric materials that have such excellent properties as those found in the PZT-based ceramics. Therefore (Na0.5Bi0.5)TiO3-based solid solutions were studied to improve piezoelectric properties. In the present study, various quantities of Bi2O3 were added into 0.99(Na0.
