文摘
(1 − x)(Pb0.97La0.02)(Zr0.5Sn0.44Ti0.06)–xBiYO3 ((1 − x)PLZST–xBYO), with x = 0.0–0.5, have been fabricated by the conventional solid-state reaction process. The phase evolution, microstructure, dielectric and energy storage properties have been investigated in detail. According to the XRD study, a secondary phase was found at room-temperature. The secondary phase was gradually increased with increasing x. The microstructure further revealed that the BYO doping leads to an increase in secondary phase. The EDS analysis revealed that Bi ions and Y ions are mainly substituted for A-site in the perovskite structure. As a result, the maximum value of energy storage density is 0.8 J/cm3, which is 2.66 times as high as that of pure PLZST ceramics.
