The effects of doping method of MgO on the characteristics of the microstructure and electric property of Ba 0.3 Sr 0.7 Zr 0.18 Ti 0.82 O 3 – x MgO 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 Ba 0.3 Sr 0.7 Zr 0.18 Ti 0.82 O 3 ceramics. Solid‐state doping with MgO was beneficial to improve breakdown strength of the ceramics, and obtained higher dielectric energy stored density.
