摘要

The Cu-doped (K_0.5Na_0.5)(Nb_0.95Ta_0.05)O₃ (KNNT) ceramics were prepared by the solid state reaction ceramic technique. The phase structure and the micro-morphology were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). There exhibits a single phase in perovskite structure, even the grain sizes increase with copper addition. The dielectric constant (ε), the planar mode electromechanical coupling factor (k_p), the piezoelectric coefficient (d₃₃), and the mechanical quality factor (Q_m) of KNNT ceramics with copper additive are 320-450, 0.21-0.41, 70-110 pC/N, 105-979, respectively.
