摘要：
In this paper, the microstructures and the dielectric properties of xSrZrO(3)-(1-x)SrTiO3 (x=0.01, 0.03, 0.05, and 0.07) ceramics were investigated. The composition can form a single-phase structure solid solution as x increases from 0.01 to 0.07, and the average grain size decreases from 15 to 2 (tin with the x increasing. With the variation of SrZrO3 content, dielectric constant, dielectric loss, and breakdown strength (BDS) of xSrZrO(3)-(1-x)SrTiO3 samples are changed. When x=0.05, the samples exhibit high BDS more than 14 kV/mn and low dielectric loss about 1 x 10(-3) with dielectric constant of 330. It can be a candidate material of energy storage for pulsed power application.
