Abstract
Ferroelectric BaZr1-xTixO3 (0 ≤ x ≤ 8) ceramic composition was synthesized by using solid state reaction method. The material was calcined at 1250 °C in air. In this work we have examined that the ferroelectric, energy storage and microwave dielectric properties of BaZr1-xTixO3 at room temperature. The XRD patterns showed that BaZr1-xTixO3 composition is of perovskite structure with a space group of Pm-3m. SEM morphology shows that increase in number of grain boundaries result in increase of polarisation. The energy storage properties were calculated from (P-E) loops by varying the electric field (range) and composition of the ceramic material. It has observed that the relative permittivity increases along with temperature. The storage energy density (Wrec) has been reported 0.043 J/cm3 , whereas efficiency (ɳ) was 57% at room temperature and 40 kv/cm at contents (x=0.06).The Barium zirconium titanate (BZT) will be an excellent candidate material for storage energy devices.
