摘要：

Lead-free 0.98(Na0.5K0.5)NbO3-0.02Ba(Zr0.52Ti0.48)O-3 ceramics modified with ZnO additive were fabricated by a conventional mixed oxide method. The ceramics were sintered at 1080 degrees C for 4h. Gradual changes in piezoelectric and dielectric properties were observed with increasing ZnO content. Relative density increases after the addition of ZnO, reaching a large value of about 95% after the addition of 1.0 mol% ZnO. Curie temperature (T-c) slightly decreases with increasing ZnO content. Dielectric constant (4118), piezoelectric constant (d(33) = 231 rho C/N) and electromechanical coupling factor (k(p) = 0.45) have slight increases after the addition of ZnO due to the improvement in the densification of the ceramics.
