Lead-free piezoelectric ceramics 0.84(K0.48Na0.52)NbO3-(0.16/5.15)K2.9Li1.95Nb5.15O15.3 + x mol％ K4CuNb8O23 (KNN-KLN16-x,x=0-1) were fabricated by conventional solid-state sintering.The effects of K4CuNb8O23 doping on the phase structure and electrical properties of the ceramics were systematically investigated.Results revealed that a small amount of K4CuNb8O23 greatly promoted the densification of the ceramics.
