极化测量表明，AgNbO 3具有极大的极化，在多晶中可达到52 μ C/cm（2）。实验还表明，AgNbO 3中较大的内部原子畸变也与电场强耦合，表明AgNbO 3系统可以实现高的压电性能。这一发现为设计一类基于AgNbO 3的新型无铅高性能压电材料开辟了道路。(c)2007年，美国物理学会。
Polarization measurements reveal that AgNbO3 has an extremely large polarization, which can reach a value of 52 mu C/cm(2) in polycrystals. Experiments also show that the large internal atom distortion in AgNbO3 is also strongly coupled to the electric field, indicating that high piezoelectric performance can be realized in AgNbO3 system. This finding opens the way to designing a new class of lead-free, high-performance piezoelectric materials based on AgNbO3. (c) 2007 American Institute of Physics.
