Abstract

Highlights: [•] Sandwich-like structure Pb0.99(Zr0.95Ti0.05)0.98Nb0.02O3 ferroelectric ceramics were designed and prepared. [•] The new structure exhibits the high ferroelectric properties, typical of dense PZT95/5 ferroelectric ceramics. [•] The new structure also exhibits high voltage breakdown resistance of porous PZT95/5 ferroelectric ceramics under shock compression. [•] The enhanced performances make the new structure promising candidate for pulsed power supply application. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Porous Pb0.99(Zr0.95Ti0.05)0.98Nb0.02O3 ferroelectric ceramics with different pore size were prepared by solid-state sintering in air. The microstructural effect on the properties has been systematically investigated by SEM, ferroelectric hysteresis, strain–electric field curves and breakdown strength measurements. The results demonstrate that the microgeometry has a subtle effect on the ferroelectric and dielectric properties. However, the results also demonstrate that the electric field induced strain and the dielectric breakdown strength decreases with the increase of pore size. [Copyright &y& Elsevier]
