Abstract

---

Due to high rising demand and price variations of the natural fuels has compelled the scientists to surge for the alternative ways to produce the sustainable energy resources, for such challenges dielectric ceramic capacitors have been explored for future generation energy materials. Herein this study a hybrid Sr0.2Na0.4Pr0.4Bi4Ti4O15:xwt%ZnO (x = 0-0.20) ceramic system has been fabricated to observe the basic insight of the material for such applications via ferroelectric, dielectric and ferroelectric analysis. Ceramic with x = 0.15wt%ZnO has shown the best merits among all the compositions with saturated polarization (PS) of 15.04 μC/cm2, stored energy density (WST) of 1.5 J/cm3,energy conversion efficiency (Æ?) of 41% and piezoelectric d33 coefficient of 21 pC/N. Moreover the ceramic has also maintained its d33 values for high temperature, even at the temperature of 500 oC, it has retained its d33 of 76% (16 pC/N) of initial value. Such characteristics of the material not only make it ideal candidate for FeRAM devices but also for high temperature piezoelectric applications.
