Abstract
The fatigue properties of Pb0.90La0.04Ba0.04[(Zr0.6Sn0.4)0.85Ti0.15]O3 (PLBZST) antiferroelectric (AFE) ceramics under submicrosecond pulsed charge–discharge cycling were investigated. 87.76% of the stored charge in the ceramics can be released in 600ns. After 106 fast charge–discharge cycles, the electrical properties, including polarization, energy density, discharge current, and released charge, did not change remarkably. Also, the cycling had little impact on the microstructure of the ceramic sample. All the results directly indicate that the obtained antiferroelectric ceramics are very promising for long-life pulsed power capacitors because of the high discharge speed and excellent fatigue resistance.
