  V2O5-doped Na0.5K0.5NbO3-LiSbO3-BiFeO3 (KNN-LS-BF) lead-free piezoelectric ceramics were prepared by the traditional sintering method, and their temperature stability was studied. Characterization of the temperature dependences of dielectric and piezoelectric properties of the V2O5-doped KNN-LS-BF ceramics showed that V2O5 doping could significantly improve the temperature stability in the temperature range of 30°C to 420°C and cause a downward shift in the orthorho...

  0.997(KNN-LS-BF)-0.003V2O5 lead-free piezoelectric ceramics were prepared by a traditional sintering method. The effects of sintering temperature on the structure and properties of the 0.997(KNN-LS-BF)-0.003V2O5 ceramics were studied. The results show that the sintering temperature exerts a distinct influence on the phase structure and properties. With the increase in sintering temperature from 1040°C to 1060°C, the main crystallographic phase changes from the ortho...
