Orthorhombic-tetragonal phase transition induced by Ta isovalent doping and its effect on fatigue characteristics of KNL-NSTx ceramics
Namsar, Orapim; Uthaisar, Chunmanus; Glaum, Julia; Pojprapai, Soodkhet (Journal article; Peer reviewed, 2018)The effect of Ta addition on the bipolar fatigue characteristics of lead-free KNL-NSTx ceramics (x = 0, 0.04, 0.07 and 0.11 mol%) is studied. Bipolar cycling up to 1 × 106 cycles leads to strong degradation of the polarization ...
