Abstract

Due to the toxic of lead content ceramics, many free piezoelectric ceramics have received much attention. To obtain high piezoelectric properties for such free piezoelectric ceramics, poling conditions are often referred. In the present work, effects of the poling electric field on the many properties of Sm doped BCZT ceramic were investigated. The samples were fabricated using a solid-state reaction technique. The XRD analysis indicated that the sample contained a mixture of phases of rhombohedral, tetragonal, and orthorhombic phases with high purity, dense, and large average grain size. A transformation from the symmetric S-E loop for the unpoled sample to an asymmetry loop for the poled sample was observed, while a slight change in the P-E shape was noted. The poling electric field showed a small effect on ɛr and kp values. However, it had large effects on HS, d33, g33, and FoM values. The low HS (9.2%), but high d33 (562 pC/N), g33 (15.55×10−3 Vm/N) and FoM (20.65 pm2/N) values indicated that this ceramic system has potential for piezoelectric and energy harvesting applications.

高压电性能改性BCZT陶瓷的极化效应

由于含铅陶瓷的毒性，许多自由压电陶瓷受到了广泛的关注。为了获得这种自由压电陶瓷的高压电性能，通常需要考虑极化条件。本文研究了极化电场对Sm掺杂BCZT陶瓷诸多性能的影响。样品是用固态反应技术制备的。XRD分析表明，样品中含有菱面体相、四方相和正交相的混合物，纯度高，致密，平均晶粒尺寸大。观察到从非极化样品的对称S-E环到极化样品的不对称环的转变，同时注意到P-E形状的轻微变化。极化电场对系数和kp值的影响较小。但对HS、d33、g33、FoM值影响较大。低HS(9.2%)，但高d33 (562 pC/N)， g33 (15.55×10−3 Vm/N)和FoM (20.65 pm2/N)值表明该陶瓷系统具有压电和能量收集应用的潜力。

期刊介绍： The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
