The effects of processing parameters and doping on phase content, microstructure, dielectric and piezoelectric properties of the materials were discussed. Experimental results show that Nb doped (Bi1/2Na1/2)TiO3 exhibits superior polarization performance over the existing lead-free ceramics with a d33 value of 122pC/N obtained when poled at 60kV/cm at room temperature. The best piezoelectric properties were achieved in (Bi1/2Na1/2)TiO3 doped with Ta having a measured d33 value of 164pC/N for samples poled at 100°C under the applied field of 50kV/cm.
