초록

[ $(Na_{0.5},\;K_{0.5})NbO_3$ ] ceramics were studied as lead free Piezoelectric materials. The addition of CdO were enhanced the sinterability of the NKN ceramics. The $(Na_{0.5},\;K_{0.47}Cd_{0.02})NbO_3$ ceramics show that electromachanical coupling factor($k_p$) is 0.34and mechanical quality factor($O_m$) is 120.
