## Abstract Lead–free ceramics (1–__x__)(K~0.5~Na~0.5~)NbO~3~–__x__ BiFeO~3~ doped with 1 mol% Fe~2~O~3~ (KNNBF/__x__) have been synthesized by pressureless sintering. With the Fe~2~O~3~ doping, the KNNBF/__x__ ceramics can be well sintered at 1085–1100 °C and exhibit a pure perovskite structure wi
