摘要/Abstract

摘要： 本文制备了0.96(K_0.48Na_0.52)(Nb_0.95-xTa_0.05Sb_x)O₃-0.04Bi_0.5(Na_0.82K_0.18)_0.5ZrO₃(即0.96KNNTS_x-0.04BNKZ, x=0.03, 0.04, 0.06, 0.07)无铅透明压电陶瓷,并探讨了不同Sb掺杂量对陶瓷压电性能和光学透明度的影响。结果表明,所有陶瓷样品均为钙钛矿结构,且Sb掺杂显著改善了陶瓷的压电性能和透明度。尤其在x=0.04时,样品的压电系数达到240 pC/N,光学透过率在波长780 nm处达到31.5%。该研究表明,通过成分设计调控,KNN基无铅陶瓷能够同时实现较好的透明度和高的压电性能,在光声成像和透明换能器等领域具有重要应用潜力。

Abstract: In this study, 0.96(K_0.48Na_0.52)(Nb_0.95-xTa_0.05Sb_x)O₃-0.04Bi_0.5(Na_0.82K_0.18)_0.5ZrO₃ (0.96KNNTS_x-0.04BNKZ, x=0.03, 0.04, 0.06, 0.07) lead-free transparent piezoelectric ceramics were prepared, and the effects of Sb doping levels on their piezoelectric properties and optical transparency were examined. All samples exhibit a perovskite structure. With increasing Sb content, both piezoelectric performance and transparency improve. Notably, at x=0.04, the piezoelectric coefficient reaches 240 pC/N, with an optical transmittance of 31.5% at 780 nm. This study demonstrates that compositional design can achieve enhanced transparency and high piezoelectric performance in KNN-based lead-free ceramics, offering significant potential for applications in optoacoustic imaging and transparent transducers.
