Abstract

A problem of fabricating piezoelectric tape ceramic is poor density after sintering. Three-step sintering (3ss) techniques were prepared to obtain tape casting ceramic with density and piezoelectric properties better than conventional sintering (CS). Pb0.976K0.012 Bi0.012[(Zr0.53 Ti0.47)0.99 Nb0.01]O3 tape ceramic was synthesized using tape casting accompanied with the sintering techniques. The green tapes were sintered on three temperature steps that are 870, 970, and 1070 °C, respectively, and compared with two temperature steps that are 870, and 1070 °C. The optimum density, dielectric properties, polarization electric field loop, piezoelectric coefficient (d33), was attained by three step sintering. The enhanced remanent polarization of 44 μC cm−1 and the recoverable energy storage density was characterized on P-E loop. In addition, d33 value of 226 pC N−1, and kp of 0.36 was enhanced to attain for the tape ceramic on 3SS.

三步烧结法增强Pb0.976K0.012Bi0.012 [((Zr0.53 Ti0.47)0.99 Nb0.01] O3陶瓷带的压电性能

摘要

压电带陶瓷的制造问题是烧结后的密度差。制备了三步烧结(3ss)技术,以获得比常规烧结(CS)更好的密度和压电性能的流延铸造陶瓷。Pb 0.976 K 0.012 Bi 0.012 [(Zr 0.53 Ti 0.470.99 Nb 0.01 ] O 3带式陶瓷是通过带式铸造和烧结技术合成的。分别在870、970和1070°C的三个温度步骤上烧结生带,并与870和1070°C的两个温度步骤进行比较。通过三步烧结获得最佳密度,介电性能,极化电场回路,压电系数(d 33)。在PE回路上表征了增强的44μCcm -1的剩余极化和可回收的储能密度。另外,在3SS上的带状陶瓷的d 33值为226pC N -1,kp为0.36。
