High-dielectric high-breakdown energy storage ceramic and preparation method thereof
The invention discloses a high-dielectric high-breakdown energy storage ceramic. The high-dielectric high-breakdown energy storage ceramic comprises the following components in percentage by mole: (1-x) Bal-ySryTi0.895Sn0.105O3-xBi1.5 ZnNb1.5O7, wherein x is more than or equal to 0.10 and less than or equal to 0.20, and y is more than or equal to O.10 and less than or equal to 0.20. According to the high-dielectric high-breakdown energy storage ceramic and the preparation method thereof of the invention, Sr and Sn elements are added into BaTiO3 to construct a three-relaxation state, and Bi1.5ZnNb1.5O7 is added before presintering to carry out pre-doping compounding with Sr and Sn, so that atoms have an antiparallel electric domain structure with a double lattice period, and the energy storage ceramic is induced to have a three-relaxation nano electric domain structure in a partial local area and generate an antiferroelectric phase at the same time.
本公开揭示了一种高介电高击穿储能陶瓷，储能陶瓷的组分及摩尔百分比含量为：(1‑x)Bal‑ySryTi0.895Sn0.105O3‑xBi1.5ZnNb1.5O7，其中，0.10≤x≤0.20，O.10≤y≤0.20。通过在BaTiO3中加入Sr‑锶、Sn‑锡元素构建三弛豫状态，并通过在预烧前加入Bi1.5Zn‑锌Nb‑铌1.5O7与Sr、Sn进行前掺复配，使得原子具有双倍晶格周期的反平行电畴结构，从而诱发储能陶瓷在部分局域内具有三弛豫纳米电畴结构的同时产生反铁电相。
