This work studies the Bi0.5Na0.5TiO3 (BNT) system doped with lanthanum (La3+) at molar concentrations 0.0, 0.3, 0.6, 0.8, 1.0, 3.0 and 6.0 . The samples were synthesized by the Sol-gel method using the acetic acid route. The bulk samples were calcined at 700 oC/1hr seeking to obtain the perovskite phase, and finally the samples were sintered at 1050 ...

Tuning the Phase Structure and Electrical Properties of BNKT‐Based Ceramics via Li+ Doping
Li+‐doped Bi0.5[Na0.84‐xK0.16Lix]0.5TiO3 lead‐free piezoelectric ceramics are fabricated. The optimized composition delivers a high piezoelectric coefficient d33 and elevated depolarization temperature Td. It also shows large electrostrain and high Curie temperature, greatly extending the working temperature range for BNT‐based piezoelectric ...
