A lead-free piezoelectric ceramic (NaBi)0.5-x(KCe)xBi2Ta2O9(NBTO-x, 0≤x≤0.15) was prepared by a solid-state reaction method. The influence of K/Ce ions co-doping content on the structure and electrical properties of NBTO ceramic was investigated. Based on the results by X-ray diffraction, a bismuth layered structure compound with m=2 is formed in all the ceramic samples. The Curie temperature TC of the samples decreases gradually with the increase of K/Ce ions co-doping content. The piezoelectric properties of the samples are improved due to K/Ce ions co-doping, The piezoelectric constant d33 initially increases and then decreases with the increase of K/Ce ions co-doping content. The ceramic with x of 0.075 exhibits the optimal properties, i.e., d33 of 19.0 pC/N, the Curie temperature TC of 735℃, dielectric loss tanδ of 0.137%, and volume density ρ of 9.113 g·cm-3. The piezoelectric constant d33 of NBTO (x of 0.075) ceramic has a good temperature stability, and the d33 of NBTO ceramic annealed at 600℃ for 2 h is still as high as 17.8 pC/N, which is 93.7% of the original value (i.e., d33=19.0 pC/N).
