In this work, (Pb0.92Ba0.05La0.02)(Zr0.68Sn0.27Ti0.05)O3 (PBLZST) antiferroelectric (AFE) ceramics with the addition of PbO–B2O3–SiO2 raw glass powder as sintering aid were prepared via the microwave sintering method. The effects of glass content on the electrical properties and energy-storage performance of the ceramics were investigated in detail. With the glass content increasing, dielectric constant of the ceramics gradually decreased, while the breakdown strength increased. A maximum recoverable energy-storage density was about 2.3 J/cm3 and the corresponding efficiency was about 76.8 % to be achieved in the ceramics with 3-wt% glass at room temperature. The energy density of the PBLZST AFE ceramic with 3-wt% glass is 1.3 times as that (1.8 J/cm3) of the pure specimens. These results indicated that the energy-storage performance of AFE ceramics could be improved by adding proper glass and selecting novel sintering method.
