Lanthanum lead zirconate titanate-based piezoelectric ceramic as well as preparation method and application thereof
The invention discloses lanthanum lead zirconate titanate-based piezoelectric ceramic as well as a preparation method and application thereof. The lead lanthanum zirconate titanate-based piezoelectricceramic is composed of Pb1-xLax (ZryTi1-y) 1-x/4O3 + a Pb (Yb0. 5Nb0. 5) O3 + b N, N is Sb2O5 or Sb2O3, x is 0.055-0.070, y is 0.55-0.61, and the total weight of Pb1-xLax (ZryTi1-y) 1-x/4O3 refers aspercentage, a ranges from 0.8-1.2%, and b ranges from 0.8-1.2%. The preparation method comprises the following steps: taking Pb3O4, La2O3, ZrO2, TiO2, Yb2O3, Nb2O5 and Sb2O5 or Sb2O3 as raw materials; ball-milling, uniformly mixing and calcining; carrying out secondary ball milling, granulating and pressing to obtain a green body; and discharging glue and sintering to obtain the lead lanthanum zirconate titanate-based piezoelectric ceramic.
本发明公开了一种锆钛酸镧铅基压电陶瓷及其制备方法与应用。所述锆钛酸镧铅基压电陶瓷的组成为：Pb1‑xLax(ZryTi1‑y)1‑x/4O3+a Pb(Yb0.5Nb0.5)O3+b N，其中，N为Sb2O5或Sb2O3，x＝0.055～0.070，y＝0.55～0.61，以Pb1‑xLax(ZryTi1‑y)1‑x/4O3总重为百分比，a为0.8～1.2％，b为0.8～1.2％。以Pb3O4、La2O3、ZrO2、TiO2、Yb2O3、Nb2O5以及Sb2O5或Sb2O3为原料；球磨混合均匀后煅烧；然后进行二次球磨，造粒压制成坯体；经排胶烧结后得到锆钛酸镧铅基压电陶瓷。
