Abstract
The dielectric constant, dielectric loss and resistivity values of the samples increase slightly with BiT addition. Good hysteresis curves are obtained in (K0.5Na0.5)NbO3-based samples only at low BiT amounts. Remnant polarization values between 9 μC/cm2 and 25 μC/cm2 are obtained for K0.48Na0.48Li0.04)(Nb0.9Ta0.1)O3 and K0.48Na0.48Li0.04)(Nb0.86Ta0.1Sb0.04)O3-based samples. With the exception of KNNLT samples where the d*33 values increase from 203 ± 7 pm/V at 0 mol% to 275 ± 6 pm/V at 0.35 mol%, the d*33 values of the samples gradually decrease with increasing BiT content. This work shows that to obtain good properties for KNN-based ceramics, only very small amounts of BiT are required.
