Ba0.3Sr0.7Zr0.18Ti0.82O3xMgO ceramics: Energy storage and breakdown

Authors


Abstract

The effects of doping method of MgO on the characteristics of the microstructure and electric property of Ba0.3Sr0.7Zr0.18Ti0.82O3xMgO ceramics were investigated experimentally. The MgO was introduced by solid-state processing and sol-gel processing, respectively. The results revealed that the doping method gives rise to differences in dielectric response and breakdown strength and energy storage density of Ba0.3Sr0.7Zr0.18Ti0.82O3 ceramics. Solid-state doping with MgO was beneficial to improve breakdown strength of the ceramics, and obtained higher dielectric energy stored density.
