Abstract

Via composition designing and sintering condition tailoring, high-density pure perovskite structure xBi(Ni_0.50Ti_0.50)O₃–0.05BiFeO₃–(0.95−x)Pb(Zr_0.50Ti_0.50)O₃ [xBNT–0.05BF–(0.95−x)PZT, x = 0.19, 0.20, 0.21, 0.22, 0.23] ceramics were prepared by solid-state sintering method with adding additional 0.5 wt% LiBO₂ sintering aid, whose sintering temperature was lower than that reported in literature. The xBNT–0.05BF–(0.95−x)PZT ceramics have mainly tetragonal structure confirmed by X-ray diffraction measurement and Raman spectroscopy, which is affected by composition and sintering condition. Broad dielectric peaks appear in all samples, and diffusive phase transition and dielectric frequency dispersion are obvious as well. The 0.20BNT–0.05BF–0.75PZT ceramics exhibit large piezoelectricity d₃₃ = 386 pC/N combined with rather high dielectric constant maximum temperature T_m = 264°C, presenting enormous application potential in the high-temperature piezoelectric-related field.

通过成分设计和烧结工艺改进定制 Bi(Ni0.50Ti0.50)O3-BiFeO3-Pb(Zr0.50Ti0.50)O3 陶瓷的性能

通过成分设计和烧结条件调整，采用固态烧结法制备了高密度纯包晶结构xBi(Ni0.50Ti0.50)O3-0.05BiFeO3-(0.95-x)Pb(Zr0.50Ti0.50)O3 [xBNT-0.05BF-(0.95-x)PZT, x = 0.19、0.20、0.21、0.22、0.23] 陶瓷，采用固态烧结法制备，并添加了 0.5 wt% 的 LiBO2 助烧剂，其烧结温度低于文献报道的温度。X 射线衍射测量和拉曼光谱证实，xBNT-0.05BF-(0.95-x)PZT 陶瓷主要具有四方结构，这种结构受到成分和烧结条件的影响。所有样品中都出现了宽介电峰，并且扩散相变和介电频率色散也很明显。0.20BNT-0.05BF-0.75PZT 陶瓷显示出较大的压电性 d33 = 386 pC/N，同时具有相当高的介电常数最高温度 Tm = 264°C，在高温压电相关领域具有巨大的应用潜力。

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
