Abstract
In this paper, after the fabrication of (Na0.5K0.5)NbO3-LiSbO3 (NKN-LS) piezoelectric ceramics, regular electric fields of AC bias were applied to the NKN-LS ceramics. Applying bias led to piezoelectric actuators losing their piezoelectric and dielectric properties. The surface microstructure and piezoelectric properties were compared and analyzed before and after the aging process. Adding LS contents retarded the aging rate of NKN-LS, compared with that of NKN ceramics.
