Influence of Calcined Temperature on the Piezoelectric Properties of (Na0.48K0.47Li0.05)NbO3 Lead-free Piezoelectric Ceramics Doped with CuO

摘要：

　　(Na0.48K0.47Li0.05)NbO3 (NKLN) Lead-free piezoelectric ceramics doped with CuO were prepared by traditional solid-state reaction method.Influence of calcined temperature on the material phase of NKLN lead-free piezoelectric ceramics doped with CuO by X-ray diffraction(XRD) and the influence of calcined temperature and sintered temperature on the properties of NKLN lead-free piezoelectric ceramics doped with CuO by others analysis method.The results show that the best calcined temperature is got,when calcined temperature is up to 850 ℃,the mixed phase disappeares,a single phase perovskites structure is formed.With the increase of calcined temperature,piezoelectric strain constant (d33)、planar electromechanical coupling factor (Kp) of NKLN lead-free piezoelectric ceramics increase first and then decrease,while only dielectric loss (tanδ) decreases first and then increases.The best calcined temperature is 850 ℃,the best sintered temperature is 1080 ℃,the NKLN lead-free piezoelectric ceramics doped with CuO with good comprehensive properties are obtained,whose d33,Kp,tans are 85 pC/N,0.3,0.038,respectively.
