Antiferroelectric ceramic material with excellent charging and discharging performance and preparation method thereof
The invention relates to an antiferroelectric ceramic material with excellent charging and discharging performances and a preparation method of the antiferroelectric ceramic material. The chemical general formula of the antiferroelectric ceramic material is (Pb0.97-xBaxLa0.02)(ZrySn1-y-zTiz)O3, the preparation method comprises the following steps: mixing a lead source, a barium source, a lanthanumsource, a zirconium source, a tin source and a titanium source, sequentially carrying out ball milling, drying and calcining, and sequentially carrying out secondary ball milling, drying, mixing witha polyvinyl alcohol solution, granulating, compression molding, glue discharge and sintering to obtain the antiferroelectric ceramic material. Compared with the prior art, the effective energy storage density of the prepared antiferroelectric ceramic material can reach 12.8 J/cm<3>, the energy storage efficiency can reach 84.2%, the current density can reach 1815 A/cm<2>, the discharge period canreach 51.6 ns, the power density can reach 327 MW/cm<3>, and very excellent charge and discharge performance is shown.
