Antiferroelectric (AFE) materials are regarded as one of the most hopeful candidates for pulse power capacitors due to their higher saturation polarization, lower remnant polarization, high power density, and fast charge− discharge speed. It is difficult to simultaneously obtain excellently the recoverable energy density (W rec ) and the energy efficiency (η) at present. In this work, PbHfO 3 AFE ceramics are processed by the cold isostatic pressure (CIP) method. It is confirmed that the CIP method can reduce the grain sizes and ameliorate the ceramic's microstructure and thus increase the average electric breakdown field strength up to 336 kV/cm compared to 269 kV/cm by the conventional solid-state (CS) method. An excellent W rec of 11.4 J/cm 3 with a high η of 88.2% is achieved in the PbHfO 3 ceramics by the CIP method at 342 kV/cm. Furthermore, it exhibits good stability in temperature and frequency and has a high discharge current density of 1557 A/cm 2 and power density of 233 MW/cm 3 with a rapid discharge speed (112 ns). Moreover, dielectric properties and Raman spectra of the sample by the CIP method are discussed and demonstrate that the sample encounters a phase transformation at 150 and 195 °C. The result in this work indicates that the PbHfO 3 AFE ceramics by the CIP method will be a potential candidate for pulse power capacitors.

Porous BaTiO3‐based relaxor ferroelectric ceramics with lamellar structure were achieved by ice templating method, and the rheological properties of ceramic slurry for freeze casting were deeply studied. Epoxy resin was then backfilled to generate ceramic–epoxy resin composites. Ceramic–epoxy composites with a lamellar structure were obtained when using a slurry with a ceramic content of 45 wt.%. The nanoindentation results showed that the introduction of ceramic materials into the epoxy resin can significantly improve the penetration resistance and hardness of the material. The dielectric and ferroelectric properties of the composites were also characterized. The interaction between the highly coupled dipoles in the polymers results in a decrease in the breakdown field strength of the composite. The dielectric constant reached up to ∼800. At 220 kV/cm, Wrec = 0.62 J/cm3, and η was ∼80%. At low frequencies, Wrec was ∼0.16 J/cm3, which indicated good stability.

Lead-free Ba 0.8 Ca 0.2 TiO 3 -xmol%Ba(Mg 1/3 Nb 2/3 )O 3 (abbreviated as BCT20-xBMN, x ¼ 0-8) ceramics are fabricated by a conventional solid-state reaction method. All BCT20-xBMN ceramics have pure perovskite phases which gradually change from tetragonal phase to cubic phase. The average grain size decreases significantly from %23 to %1.2 μm with the increase in BMN content. The T m corresponding to the dielectric maximum of BCT20-xBMN decreases with the increase in x, and the room temperature dielectric constant increases significantly. The recoverable energy storage density W rec and efficiency η% are enhanced to 0.17 J cm À3 and 81.3% for BCT20-6BMN due to the reduced remanent polarization by BMN doping. The W rec increases with increasing temperature and shows peak values near the T m . The η% of BCT20-6BMN and BCT20-7BMN has good temperature stability due to enhanced relaxor behavior.
