摘要：
(1-x)Ba(Zr0.2Ti0.8)O3-x Na0.5Bi0.5TiO3 (x = 0, 10, 20 30, 40, 50 mol%) (BZTN) ceramics are prepared by the traditional solid phase method. All BZTN ceramics exhibit a pseudo-cubic BZT based perovskite structure. Both the average grain size and the relaxor ferroelectricity of BZTN ceramics gradually increase with increasing NBT content. The W-rec of 3.22 J/cm(3) and eta of 91.2% is obtained for the BZTN40 ceramic at 241 kV/cm. BZTN40 ceramic also exhibits good temperature stability from room temperature to 150 degrees C and frequency stability from 1 Hz to 100 Hz. A P-D of 0.621 J/cm(3) and a t(0.9 )of 82 ns is obtained for the BZTN40 ceramic at 120 kV/cm. BZTN ceramics show application potential in energy storage and pulse power capacitors.
