Piezoelectric ceramic material with stable capacitance temperature and preparation method thereof
The invention discloses a piezoelectric ceramic material with stable capacitance temperature and a preparation method thereof. The composition of the piezoelectric ceramic material is xPb (Yb<0.5>Nb<0.5>) O<3> (1-x) Pb (Zr<0.49> Ti<0.51>) O<3+y wt%>Ba<1-c-d>SrMgSnZrTi<1-a-b>O<3>, wherein the value of x ranges from 0.02 to 0.05, the value of y ranges from 0.5 to 3, the value of a rangesfrom 0.05 to 0.15, the value of b ranges from 0.05 to 0.1, the value of c ranges from 0.01 to 0.05, and the value of d ranges from 0.01 to 0.05. According to the invention, the piezoelectric ceramicbody formula is doped with a component of which the dielectric constant is reduced along with the temperature rise, so that the change rate of the dielectric constant of the piezoelectric ceramic material along with the temperature is reduced, the manufacturing cost is low, and volume production of the piezoelectric ceramic with stable capacitance temperature is easy to realize.
本发明公开一种容温稳定性压电陶瓷材料以及制备方法，该压电陶瓷材料的组成为xPb(YbNb)O(1‑x)Pb(ZrTi)O+ywt％BaSrMgSnZrTiO，其中，x的取值范围为0.02～0.05，y的取值范围为0.5～3，a的取值范围为0.05～0.15，b的取值范围为0.05～0.1，c的取值范围为0.01～0.05，d的取值范围为0.01～0.05。本发明通过在压电陶瓷本体配方中掺杂介电常数随温度升高而降低的组分，以降低压电陶瓷材料介电常数随温度的变化率，制作成本低，易于实现批量生产的容温稳定的压电陶瓷。
