چکیده

In this study, the effects of sintering temperature on microstructure, dielectric and piezoelectric properties are investigated for non-stoichiometric (Na0.48K0.473Li0.04Sr0.007)(Nb0.883Ta0.05Sb0.06Ti0.007)O3 (NKLNTSST) ceramics. The results suggest that enhanced owing to more normal ferroelectric characteristics, higher density, uniform grains presence polymorphic phase transition regions, which observed with an increase in up 1080?C. weakened larger degree diffuse cationoxygen-vacancy pairs above best including kp = 40%, d33 288 pC/N, ?max 72.12, loss 2.57%, Ec 13.45 kV/cm Pr 10.23 ?C/cm2 obtained at

Low-temperature sintering of MnO2-doped PZT–PZN Piezoelectric ceramics

The effect of MnO2 addition on the microstructural evolution and piezoelectric properties of low temperature sinterable PZT–PZN ceramics was investigated. When a small amount of MnO2 (≤0.5 wt% ) was added, the Mn ions were homogeneously dissolved in the PZT– PZN ceramics, leading to full densification at a temperature as low as 930 °C. However, the further addition of MnO2 hindered the densific...

Electrical properties of lead-free 0.98(Na0.5K0.5)NbO3-0.02Ba(Zr0.52Ti0.48)O3 piezoelectric ceramics by optimizing sintering temperature

Lead-free 0.98(Na0.5K0.5)NbO3-0.02Ba(Zr0.52Ti0.48)O3 [0.98NKN-0.02BZT] ceramics were fabricated by the conventional mixed oxide method with sintering temperature at 1,080°C to 1,120°C. The results indicate that the sintering temperature obviously influences the structural and electrical properties of the sample. For the 0.98NKN-0.02BZT ceramics sintered at 1,080°C to 1,120°C, the bulk density i...
