摘要
Multifunctional antiferroelectric (Pb0.92-xBa0.05La0.02Dyx)(Zr0.68Sn0.27Ti0.05)O-3 multilayer ceramic capacitor (MLCC) was prepared successfully by the tape-casting method. The MLCC with 10-thick layers exhibits compact structure, excellent energy-storage, and strain properties. For energy-storage performance, the pulsed discharge current reveals that the stored energy can be released in a quite short time of about 600ns. The maximum discharge energy density was obtained in the sample with x=0.04 at 300kV/cm, which was 3.8J/cm(3) calculated by the hysteresis loop and 2.7J/cm(3) by the pulsed discharge current, respectively. Meanwhile, the MLCC possesses large strain property, where the sample with x=0.04 shows a high field-induced strain of 0.71% at room temperature. In addition, the temperature dependence of energy-storage and strain demonstrates that the MLCC has good temperature stability. The results indicate that the multifunctional MLCC can be a promising candidate for the application in energy and sensor fields.
