Modified lead zirconate titanate piezoelectric ceramic added with bismuth antimonate and preparation method of modified lead zirconate titanate piezoelectric ceramic
The invention discloses a modified lead zirconate titanate piezoelectric ceramic added with bismuth antimonate and a preparation method thereof, and relates to the technical field of piezoelectric ceramics, Sr/La co-doping substitution is carried out on the A site of PZT ceramic, BiSbO3 and a small amount of CeO2 and Sm2O3 are added for doping modification, and the formula molecular formula of the piezoelectric ceramic is (1-u) Pb1-x-y SrxLay (ZrzTi1-z) O3-uBiSbO3-vwt% CeO2-hwt% Sm2O3. In the formula, 0 < = x < = 0.5, 0 < = y < = 0.5, 0.3 < = z < = 0.7, 0 < = u < = 0.3, 0 < = v < = 0.3, and 0 < = h < = 0.3. After the technical scheme is adopted, the dielectric loss of the PZT ceramic can be reduced while the high-voltage performance can be maintained, and generation of noise in the signal output process is reduced.
本发明公开了一种外加锑酸铋的改性锆钛酸铅压电陶瓷及其制备方法，它涉及压电陶瓷技术领域，其在PZT陶瓷的A位进行Sr\La的共掺取代，同时外加BiSbO3和少量的CeO2和Sm2O3进行掺杂改性，其配方分子式为：(1‑u)Pb1‑x‑ySrxLay(ZrzTi1‑z)O3‑uBiSbO3‑vwt％CeO2‑hwt％Sm2O3。其中：0≤x≤0.5、0≤y≤0.5、0.3≤z≤0.7、0≤u≤0.3、0≤v≤0.3、0≤h≤0.3。采用上述技术方案后，本发明能够保持高压电性能的同时，降低PZT陶瓷的介电损耗，减少信号输出过程中噪声的产生。
