The effects of the tape casting processing on the characteristics of the microstructure and the electric properties of Ba0.3Sr0.7Zr0.18Ti0.82(BSZT)-0. 02MgO were investigated experimentally. The BSZT powder was fabricated by sol-gel method and the MgO was introduced by the solid-state process. The results indicated that proper firing temperature and tape casting method were effective to improve the electric properties, especially breakdown strength and the energy-storage density of the ceramics. The breakdown strength and energy-storage density of the ceramics reached 233. 33 kV/cm and 1. 539×106 Jm-3, respectively.
