Piezoelectric ceramic material, preparation method thereof and piezoelectric device
The invention relates to a piezoelectric ceramic material, a preparation method thereof and a piezoelectric device. The chemical formula of the piezoelectric ceramic material is (1-x) Pb (Mg1/3Nb2/3) O3-xPbTiO3: y (La2O3 + SrCO3), x is more than or equal to 0.30 and less than or equal to 0.34, y is more than 0.00 and less than or equal to 0.03, and x and y are molar ratios. Compared with (1-x) Pb (Mg1/3Nb2/3) O3-xPbTiO3 ceramic without introduction of La2O3 and SrCO3, the piezoelectric ceramic material provided by the technical scheme of the invention has higher piezoelectric property, and tests prove that the piezoelectric coefficient d33 of the piezoelectric ceramic material provided by the technical scheme of the invention can reach 730pC/N. In addition, the invention also comprises a preparation method of the piezoelectric ceramic material and a piezoelectric device comprising the piezoelectric ceramic material.
本发明涉及一种压电陶瓷材料及其制备方法和压电器件。压电陶瓷材料的化学式为(1‑x)Pb(Mg1/3Nb2/3)O3‑xPbTiO3:y(La2O3+SrCO3)，其中0.30≤x≤0.34，0.00＜y≤0.03，x和y为摩尔比。与不引入La2O3和SrCO3的(1‑x)Pb(Mg1/3Nb2/3)O3‑xPbTiO3陶瓷相比，本发明技术方案的压电陶瓷材料具有更高的压电性能，经过试验验证，本发明技术方案的压电陶瓷材料的压电系数d33可达730pC/N。此外，本发明还包括一种上述压电陶瓷材料的制备方法和包括上述压电陶瓷材料的压电器件。
