摘要:

采用固相法制备了Ce和Sr复合掺杂的Bi4Ti2.92Nb0.08O12.04(BTN+0.5x%CeO2+0.5x%SrCO3,0≤x≤1.5,质量分数)铋层状高温无铅压电陶瓷,研究了不同含量的Ce和Sr掺杂对BTN系陶瓷微观结构及电性能的影响。结果表明:样品均为单一的铋层状结构相,Ce和Sr的引入明显提高了陶瓷的压电性能。当掺杂量x=0.9时,样品具有最佳性能:压电常数d33=29pC/N,平面机电耦合系数kp=8.77%,介电损耗tanδ=0.13%,剩余极化强度Pr=15.87μC•cm-2和Curie温度TC=627℃。此外,该组分陶瓷样品具有良好的压电稳定性,表明该材料在高温领域下具有良好的应用前景。

Bismuth layer-structured high-temperature lead-free piezoelectric ceramics of Ce and Srco-doped Bi4Ti2.92Nb0.08O12.04 (BTN+0.5x%CeO2+0.5x%SrCO3, 0≤x≤1.5, mass fraction) were fabricated by a solid-state reaction method. The effect of doping content of Ce and Sr on the microstructure and electrical properties of the BTN ceramics was investigated. The results show that all the ceramic samples have a single phase of bismuth oxide layered structure. The piezoelectric activity of the ceramics is improved via the modification of Ce and Sr. The ceramic with the doping content x of 0.9 exhibites the optimum electrical properties, i.e., the piezoelectric constant d33 of 29pC/N, planar electromechanical coupling factor kp of 8.77%, dielectric loss tan δ of 0.13% , remanent polarization Pr of 15.87 μC/cm2 and the Curie temperature TC of 627℃. Inaddition, the component ceramic sample possesses a high piezoelectric stability, showing that the ceramic is a potential material for high-temperature applications.
