Abstract

(1-x)Ba(Zr0.2Ti0.8)O3-xSbNbO4 ceramics were synthesized by solid state reaction method. The samples were investigated on the crystalline structure, dielectric and ferroelectric properties. XRD patterns exhibited the microstructure and tetragonal phase for all samples with sintering temperature at 1150 oC. The results showed that SbNbO4 1 mol% coexisted between tetragonal to cubic phases. The dielectric constant was obviously increased from adding SbNbO4 3 mol%, while the dielectric loss slightly decreased. The P-E loops of sample ceramic showed the ferroelectric behaviour, as well as normally ferroelectric and relaxor ferroelectric. In addition, the good ferroelectric properties exhibited Ec = 2.80 kV∙cm–1, Pr = 7.24 μC cm–2 for SbNbO4 4 mol% which it originated to the contributions of the perovskite structure (tetragonal phase).
