文摘

0.475BNT-0.525BCTZ-xwt%MgO ceramics were densified by microwave sintering method. The substitution of Ti4+ by Mg2+ and the reaction between the matrix and MgO were suppressed by microwave sintering. The x=5 sample exhibits a high dielectric breakdown strength of 17.91 kV/mm. A high energy storage density of 1.37 J/cm3 was obtained in 0.475BNT-0.525BCTZ-5wt%MgO ceramic.
