The orthorhombic structure of (Na0.5K0.5)NbO3 (NKN) ceramics was maintained when ZnO was added. NKN ceramics have a porous microstructure and dissolve when they are exposed to water. However, as ZnO was added, a dense microstructure was developed and deliquescence was not observed. The mechanical quality factor (Q m) and coercive field (E c) increased with the addition of ZnO, indicating that ZnO acted as a hardener in the NKN ceramics. The dielectric constant (ε T 3/ε o), piezoelectric constant (d 33) and electromechanical coupling factor (k p) increased when a small amount of ZnO was added, which might be due to the increase in density. The good dielectric and piezoelectric properties of ε T 3/ε o = 500, d 33 = 121 and k p=0.4 were obtained for the NKN ceramics with 1.0 mol% ZnO.
