Lead-free piezoelectric ceramics 0.96(K0.5Na0.5)(Nb0.96Sb0.04)-0.04LiTaO3 (96KNNS-4LT) have been prepared by using the conventional technique. The effect of the sintering temperature on the piezoelectric properties of 96KNNS-4LT ceramics was studied. The X-ray diffraction (XRD) and scanning electron microscope (SEM) show that all the ceramics possess a pure perovskite phase and dense microstructure...
0.99[(NaxK1-x)Nb0.955O3-0.045LiSbO3]-0.01CaTiO3 (NKNLS-CT) lead-free piezoelectric ceramics have been prepared by the conventional mixed oxide method. The effect of the K/Na ratio on the electrical properties of NKNLS-CT ceramics was investigated. When x = 0.52, the ceramics possess optimum properties: piezoelectric constant d33=266 pC/N, planar electromechanical coupling factors kp=48.7 %. These...
The new lead-free ferroelectrics with composition of 0.995[(K0.5Na0.5)0.95Li0.05](Nb0.95Sb0.05)O3-0.005BaTiO3 (0.995KNLNS-0.005BT) were prepared by using normal sintering method, and the ferroelectric relaxor behavior and electrical properties of the ceramics were systematically studied. The ceramics exhibit typical ferroelectric relaxor behavior, that is, the dielectric peaks become increasingly...
In this paper, the semiconducting mechanism of BaTiO3 semiconducting ceramics with ABO3 perovskite structure was investigated. The PTCR characteristics of BaTiO3 semiconducting ceramic with lower resistivity have been studied by substituting in A position via doping with single donor Sb2O3, composite substituting in A and B position via doping with double donor Y2O3 + Nb2O5, and substituting in oxygen...
