摘要：

The orthorhombic phase Pb0.97La0.02(Zr0.93Sn0.05Ti0.02)O-3 (PLZST) and the tetragonal phase (Pb0.93Ba0.04La0.02) (Zr0.65Sn0.3Ti0.05)O-3 (PBLZST) were composited by the conventional solid state method to acquire high energy storage density and high thermal stability. X-ray diffraction spectra revealed the coexistence of orthorhombic and tetragonal structure, indicating that the ceramics were successfully composited. The component ratio of PLZST/PBLZST significantly influenced the thermal stability as well as the energy storage density due to the opposite energy storage performance-temperature trend of PLZST and PBLZST. The phase composition, microstructure and electric properties were discussed to explain the performance in the ceramic composites. High energy storage density of 3.20 +/- 0.02 J/cm(3) at 20 degrees C with a variation < 15% over a temperature range from 20 degrees C to 150 degrees C were found in the ceramic composite with a PLZST/PBLZST ratio of 55:45. This work provide an effective method to broaden applications of energy storage ceramics in high temperature.
