本文首次研究了(x)Pb(In1/2Nb1/2)O-3:(1-x)Pb(Mg1/3Nb2/3)O-3 [PIMN(x/100-x)]固溶体系中（x =50 mol%）陶瓷的加工和电性能。球团在1100℃下烧结，得到具有98%理论密度的相纯钙钛矿陶瓷。在26℃时，陶瓷表现出典型的弛豫铁电特性，最大介电常数为8056，在25℃时存在轻微的极化滞后，在峰值48 kV/cm时，最大诱导极化为23.95 μ C/cm(2)，剩余极化为1.2 μ C/cm(2)。测量应变和电致伸缩系数，其取值范围分别为x(33) = 8.12 x 10（-4）和Q(33) = 1.42 x 10(-2) m(4)/C-2。x（33）的低迟滞和低P-r值使该盖溶液具有进一步研究的吸引力。(C) 1999 Elsevier Science B.V.版权所有
This paper describes the first study on processing and electrical properties of ceramics in the (x)Pb(In1/2Nb1/2)O-3:(1-x)Pb(Mg1/3Nb2/3)O-3 [PIMN(x/100-x)] solid solution system with x=50 mol%. Pellets were sintered at 1100 degrees C resulting in phase-pure perovskite ceramics with 98% theoretical density. These ceramics displayed typical relaxer ferroelectric behavior with a maximum dielectric constant of 8056 at 26 degrees C. A slight polarization hysteresis was observed at 25 degrees C. A maximum induced polarization of 23.95 mu C/cm(2) and remanent polarization of 1.2 mu C/cm(2) at the peak field level of 48 kV/cm was measured. The strain and electrostriction coefficient were measured, the values were in the range of x(33) = 8.12 X 10(-4) and Q(33) = 1.42 X 10(-2) m(4)/C-2, respectively. The low hysteresis in x(33) and low values of P-r make this lid solution attractive for further study. (C) 1999 Elsevier Science B.V. All rights reserved.
