Abstract: Lead free 0.55(Ba0.9Ca0.1) TiO3-0.45Ba (Sn0.2Ti0.8) O3 (BCT-BST) ceramic is synthesized by three different techniques viz solid state method, sol-gel method and molten-salt method. The prepared BCT-BST ceramic samples exhibited cubic crystal structure on X-ray powder diffraction analysis. The morphology of the samples is analyzed using transmission electron microscope. The lattice interactions with ultrasonic waves and morphotropic phase boundary at 70oC is confirmed from elastic and anelastic studies of the ceramic. High piezoelectric coefficient d33 of 623 pC/N is achieved in the prepared BCT-BST ceramics.
