| 摘 要： | NaNbO_3-Co_2O_3 co-added PZN-PZT(PZCNNT)ceramics were prepared using conventional solid state reaction.The piezoelectric and dielectric properties were measured.The experimental results show that the addition of 0.3mol% Co_2O_3 leads to low dielectric loss(tgδ)in PZCNNT ceramics and the proper addition of NaNbO_3 not only improves piezoelectric properties but also decreases intensively dielectric loss and mechanical loss.The optimal ceramic having d_(33)=310 pC/N,k_p=0.59,ε_r=985,tgδ=0.0034,Q_m=1380 was obtained.
