摘要：
In the present study, Sr0.7Bi0.2TiO3 is mixed with [(K0.5Bi0.5)(Mg1/3Nb2/3)O-3] to form a solid solution of [(1 - x)SBT-x(KB)(MNb), x = 0.02, 0.04, 0.06, 0.1]. From the XRD results, it is indicated that KB is the main substituent for SBT ceramic at the A-site. The breakdown strength (BDS) of ceramic gradually increases with an increase in doping content and achieves a high value of 280 kV/cm for x = 0.06. In addition, the 0.94SBT-0.06(KB)(MNb) ceramic shows excellent temperature stability (-55 to 140 degrees C), a high recoverable energy density (W-d)-2.6 J/cm(3), and an efficiency (eta)-88% at 280 kV/cm. Therefore, 0.94SBT-0.06(KB)(MNb) ceramic is one of the possible materials for energy storage capacitor applications.
