Lead free (1-x)(Bi0.5Na0.5)TiO3–xCaTiO3 ceramics were prepared by solid state reaction route taking five different compositions with x = 0.01, 0.03, 0.05, 0.07 and 0.09. Perovskite-like single-phase compounds were confirmed from X-ray diffraction analysis. Also the X-ray diffraction analysis confirmed that with the increase in the concentration of CT, the lattice parameter decreases. The Raman spectroscopy study confirmed that, the lattice parameters changed, which well aligned with XRD study. Surface morphology was successfully studied from SEM image which conformed that the grain size and shape changed with increasing CT concentration. Dielectric measurements conformed that, Tc increases, dielectric constant decreases and dielectric loss increases with increase in wt% of CT.
