Abstract
The dielectric, ferroelectric, and piezoelectric properties of ceramics from the Pb0.88Sr0.12 Zr0.54Ti0.44Sb0.02O3 system were investigated as a function of annealing time after being prepared via the solid-state method. Following the annealing process, a shift in the ferroelectric to paraelectric transition temperature (Tm) was observed. In addition, a high relative permittivity >24300 at Tm was recorded for the 64 h annealed sample which was 52% higher than that of the as-sintered samples. The increased annealing time produced an enhancement in the ferroelectric properties and a high piezoelectric coefficient (d33) of 670 pC/N was also observed for the 64 h annealed sample.
