Na 0.5 K 0.5 NbO 3 (NKN) and Mn-doped NKN crystals, which are one of the promising candidates of lead-free piezoelectric materials, were grown by using a floating zone (FZ) method. The resulting crystal growth was compared with crystal growth that resulted from using a flux method in a previous stud

## 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 Β°C and exhibit a pure perovskite structure wi
