Abstract

Dense K4CuNb8O23 modified (Na0.5K0.5)NbO3 (NKN:KCN) ceramics were synthesized by using conventional oxide mixing process. The maximum mechanical quality factor Qm of NKN:KCN ceramics reaches up to 1150, the piezoelectric constant d33 and the planar electromechanical coefficient kp still maintain relatively high levels, which are about 100 pC/N and 40%, respectively. Middle frequency (455 kHz) lead-free resonators were fabricated by using NKN:KCN, and remarkable improvements in resonance characteristics were found by KCN doping. [ABSTRACT FROM AUTHOR]
