In the present work, a solid solution of lead free 0.90[(Bi{sub 0.96}La{sub 0.04}){sub 0.5}Na{sub 0.5}TiO{sub 3}]-0.10(Ba{sub 0.90}Ca{sub 0.10}TiO{sub 3}] (abbreviated as 0.90BLNT-0.10BCT) piezoceramics has been synthesized by semi-wet technique. X-ray diffraction pattern confirms the phase formation. Rietveld refinement of XRD data demonstrates the coexistence of rhombhohedral (R3c) + tetragonal (P4mm) phase at room temperature. Raman spectrum is also support the above analysis. A large enhancement in bipolar strain of 0.12 % and calculated normalized strain, d*{sub 33} (defined as S{sub max}/E{sub max}) ~ 265 pm/V at 40kV/cm has been observed for this composition as compared to pure BLNT specimen, which make possible it as a potential lead-free candidates for piezoelectric applications.
