研究了铌掺杂锆锡钛酸铅铁电陶瓷Pb0.99Nb0.02[(Zr0.90Sn0.10)0.96Ti0.04]0.98O3(PZST 90/10-4-2Nb)在静水压(0300 MPa)下的电荷释放量和介电性能. 对压力诱导的低温铁电三方(FR(LT))反铁电正交(AO)相变进行了研究. PZST 90/10-4-2Nb铁电陶瓷分为未极化、极化和压力去极化三种. 极化PZST 90/10-4-2Nb陶瓷FR(LT)AO相变过程中,电荷释放量为29.3 C/cm2,相变压力为140 MPa. 介电性能表明:极化PZST 90/10-4-2Nb陶瓷相变压力为136 MPa,而未极化陶瓷相变压力为104 MPa,压力去极化陶瓷未表现出明显的相变特征.Nb-doped lead zirconate stannate titanate ferroelectric ceramic with composition Pb0.99Nb0.02[(Zr0.90Sn0.10)0.96Ti0.04]0.98O3 (PZST 90/10-4-2Nb) is studied in a hydraulic pressure range of 0300 MPa by released charge and dielectric measurements. Pressure-induced low temperature phase transition from ferroelectric rhombohedral (FR(LT)) structure to antiferroelectric orthorhombic (AO) strueture is investigated. Unpoled, poled and pressure-depolarized PZST 90/10-4-2Nb ferroelectric ceramics are used. The released charge quantity is 29.3 C/cm2 and the threshold pressure is 140 MPa during the phase transformation from FR(LT) structure to AO strueture. Dielectric properties show that the threshold pressure of the phase transformation from FR(LT) structure to AO structure is 136 MPa for poled ceramic and 104 MPa for unpoled ceramic. Obvious characteristic of phase transformation is not observed in pressure-depolarized ceramic.
