Enhanced performances of sandwich structure Pb-0.99(Zr0.95Ti0.05)(0.98)Nb0.02O3 ferroelectric ceramics for pulsed power application
Sandwich-like structure Pb-0.99(Zr0.95Ti0.05)(0.98)Nb0.02O3 ferroelectric ceramics were prepared by die-pressing technique and the microstructure, dielectric and ferroelectric properties were investigated in the present study. It is found that the controlled pores can be well sustained in the porous layer, and for the sandwich-like structure, high breakdown strength, resistivity and low dielectric loss are simultaneously achieved. The resulting enhanced performances make the sandwich-like structure ferroelectric ceramics promising candidate for pulsed power supply application. (C) 2013 Elsevier Ltd. All rights reserved.
