Relaxor Ferroelectric Ceramics

ABSTRACTPb(Sc1/2Ta1/2)O3 (PST) relaxor ferroelectric ceramics were investigated widely in the past decades for their excellent pyroelectric, ferroelectric and dielectric properties and comprehensive applications in uncooled focal plane arrays infrared detectors and other electronic devices. However, some other ferroelectrics could be added into the PST ceramics to form the complex perovskite ferroelectrics with better electric properties. In this paper, (1-x)PST-xPZT(PSTZT) relaxor ferroelectric ceramics were prepared by wolframite precursor process (named two-step -sintering method, TSSM). The experiment results showed that the PSTZT ceramics with pure perovskite structure could be prepared by using TSSM. The temperature dependence of permittivity and dielectric loss of PSTZT ceramics were investigated in detail, which indicated that PSTZT ceramics showed partly diffusive phase transition with little frequency dispersion. The dielectric and pyroelectric properties of PSTZT ceramics were also investigated and discussed.

Relaxor Ferroelectric Ceramics

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.

We prepared highly transparent relaxor ferroelectric ceramics based on (K0.5Na0.5)NbO3 using a pressure-less solid-state sintering method without using hot isostatic pressing and spark plasma sintering.
