چکیده انگلیسی
The orthorhombic phase Pb0.97La0.02(Zr0.93Sn0.05Ti0.02)O3 (PLZST) and the tetragonal phase (Pb0.93Ba0.04La0.02)(Zr0.65Sn0.3Ti0.05)O3 (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 3.20â±â0.02âJ/cm3 at 20â°C with a variation <15% over a temperature range from 20â°C to 150â°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.
