Paper Title:
The Crystalline, Dielectric and Pyroelectric Properties of (1-x)Pb(Sc0.5Ta0.5)O3-xPb(Zr0.52Ti0.48)O3 Relaxor Ferroelectric Ceramics
  Abstract

The (1-x)PST-xPZT(PSTZT) complex perovskite relaxor ferroelectric ceramics were prepared by wolframite precursor process(named two-step-sintering method, TSSM) and conventional oxides mixing method (named one-step-sintering method, OSSM), respectively. The experimental results demonstrated that pure perovskite PSTZT ceramics could be acquired by OSSM or TSSM. The temperature dependence of permittivity and dielectric loss of PSTZT ceramics indicated that PSTZT ceramics are relaxor ferroelectric ceramics with a complete diffusive phase transition. The pyroelectric properties of PSTZT ceramics prepared by OSSM and TSSM were also investigated via quiet-state method. It was found that the larger the x value of (1-x)PST-xPZT is, the lower the pyroelectric coefficient of PSTZT ceramics is. The pyroelectric coefficient of 0.9PST-0.1PZT ceramics is about (8~25) × 10-8C/cm2·K at room temperature. The pyroelectric figure of merit of PSTZT ceramics was also discussed.
