Piezoelectric characteristics of low temperature sintering Pb(Ni1/3Nb2/3)O3–Pb(Zr1/2Ti1/2)O3 ceramics as a function of Pb(Mn1/3Sb2/3)O3 substitution

Abstract

In this study, in order to develop the composition ceramics for multilayer ceramic for ultrasonic nozzle and ultrasonic actuator application, Pb(Mn 1/3 Sb 2/3 )O 3 (abbreviated as PMS) substituted Pb(Ni 1/3 Nb 2/3 )O 3 -Pb(Zr,Ti)O 3 (abbreviated as PNN-PZT) ceramics were fabricated using two-stage calcinations method and Li 2 CO 3 , Na 2 CO 3 and ZnO as sintering aids, and their piezoelectric and dielectric characteristics were investigated. With the increase of the amount of PMS substitution, electromechanical coupling factor (k p ), and mechanical quality factor (Q m ) of specimens showed the maximum value at 3 mol% substituted specimen while dielectric constant (ɛ r ) was decreased. At the sintering temperature of 900°C, the density, ɛ r , k p , and Q m of 3 mol% PMS substituted PNN-PZT composition ceramics showed the optimal values of 7.92 [g/cm 3 ], 959, 0.584, and 1003, respectively, for low loss multilayer piezoelectric actuator application.

Properties of Low‐Temperature Sintering PNN–PMW–PSN–PZT Piezoelectric Ceramics with Ba(Cu1/2W1/2)O3 Sintering Aids

“…A well‐saturated ferroelectric hysteresis loop at a maximum applied voltage of 2.5 kV gives saturation polarization ( P s ) of 28.2 μC/cm 2 , remanent polarization ( P r ) of 21.0 μC/cm 2 , and coercive field ( E c ) of 7.75 kV/cm. The ferroelectric properties of the samples are comparable with other reported P r (20.73, 11.18, and 27 in μC/cm 2 ) and E c (9.12, 10.39, and 14.5 in kV/cm) of 900°C sintered Pb‐based perovskite ceramics, respectively …”

“…The composition ceramics PNN–PMW–PSN–PZT–BCW have piezoelectric constant ( d 33 ), electromechanical coupling factor ( k p ), and mechanical quality factor ( Q m ) of 551 pC/N, 0.52, and 52, respectively. The ceramics were sintered as low as 900°C using economical industrial oxide powders, and have good piezoelectric properties compared with other reported 900°C sintering Pb‐based perovskite ceramics …”

“…As an economical material, pure Ag can be used as internal electrode of the multilayer ceramics which needs to be sintered at low temperatures of about 900°C . Some sintering aids such as ZnO, Na 2 CO 3 , CaCO 3 , Li 2 CO 3 , Bi 2 O 3 , and CuO were added to develop the low‐temperature sintering piezoelectric ceramics …”

“…압전세라믹스 중 높은 에너지 변환 효율을 가지는 PZT계 세라믹스는 압전변압기, 압전액츄에이터 및 압전모터, 필터 및 레조네이터, 초 음파 진동자 등에 넓게 응용되고 있다. 그러나 PZT 계 세라믹스는 중량비의 60%이상이 인체 및 환경에 유해한 Pb가 차지하고 있어 환경오염에 대한 문제가 제기되고 있는 실정이다 [1,2]. PZT계 압전세라믹스 를 대체할 세라믹스에 대한 연구로 Bi-layer type, (BiNaK)TiO3, (NaK)NbO3, tungsten-bronze type 압 전세라믹스를 중심으로 많은 연구가 진행되고 있다.…”
