The invention relates to a rare earth doped lead-based piezoelectric ceramic, a preparation method thereof and a piezoelectric device. The chemical formula of the rare earth doped lead-based piezoelectric ceramic is Pb1-x (Mg1/3Nb2/3) 1-yTiyO3: 0.015 Sm, wherein x is greater than or equal to 0.1% and less than or equal to 0.8%, and y is greater than or equal to 0.30 and less than or equal to 0.35. Compared with the traditional rare earth doped lead-based piezoelectric ceramic with a chemical dosage ratio, the rare earth doped lead-based piezoelectric ceramic in the technical scheme has the advantages that the content of lead is reduced, and the contents of precipitated lead ions and second-phase oxide can be correspondingly reduced, so that the influence of the second-phase oxide on the piezoelectric property of the piezoelectric ceramic is reduced, and the piezoelectric property of the piezoelectric ceramic is improved. The piezoelectric property of the rare earth doped lead-based piezoelectric ceramic can be enhanced. In addition, the invention also relates to a preparation method of the rare earth doped lead-based piezoelectric ceramic, and a piezoelectric device comprising the rare earth doped lead-based piezoelectric ceramic.
本发明涉及一种稀土掺杂铅基压电陶瓷及其制备方法和压电器件。稀土掺杂铅基压电陶瓷的化学式为Pb1‑x(Mg1/3Nb2/3)1‑yTiyO3:0.015Sm，其中0.1％≤x≤0.8％，0.30≤y≤0.35。与传统的化学剂量比的稀土掺杂铅基压电陶瓷相比，本发明技术方案的稀土掺杂铅基压电陶瓷中，减少了铅的含量，能够相应减少析出的铅离子以及第二相氧化物的含量，从而降低第二相氧化物对压电陶瓷的压电性质的影响，能够增强稀土掺杂铅基压电陶瓷的压电性质。此外，本发明还涉及一种稀土掺杂铅基压电陶瓷的制备方法、以及包括上述稀土掺杂铅基压电陶瓷的压电器件。
