Abstract
Lead-free Na0.5K0.5NbO3 + 0.5 mol% NiO+y mol% CuO (y = 0∼3) piezoelectric
ceramics have been prepared by conventional solid state reaction technique. The crystal
structure and microstructure were analyzed using X-ray diffraction and scanning
electron microscopy, respectively. The results indicated that the co-doping of NiO and
CuO was very effective in densification of ceramics. The KNN ceramics co-doped with
0.5 mol% NiO and 2 mol% CuO exhibited high mechanical quality factor of Qm = 1556
