Abstract
This project dealt with the preparation of Lead-free piezoelectric ceramics (1- x)Bi0.5Na0.5TiO3 -xBaTiO3 that have been prepared by a conventional solid state reaction method , four different composition of (1- x)Bi0.5Na0.5TiO3 -xBaTiO3 were prepared in which x have values 0, 0.04,0.06,0.08. After the addition of BaTiO3 into Na0.5Bi0.5TiO3, the ceramics exhibit strong piezoelectric property at MPB, the ceramics with x = 0.06 exhibit optimum piezoelectric and dielectric properties. X-ray diffraction analysis of the different composition has been carried out to know about the phases. Dielectric measurement was carried out for different compositions. The samples were poled at a voltage 3-4 KV and the piezoelectric measurements were carried out. The micro-structural characterization was done by Scanning Electron Microscopy.
