BiFeO3-doped (Na0.5K0.5)NbO3 lead-free piezoelectric ceramics
Science and Technology of Advanced Materials, 2008 Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3-xBiFeO3 (x=0~0.07) were synthesized by the solid-state reaction. Differential scanning calorimetry (DSC) measurements revealed that an increase in the amount of BiFeO3 dopant resulted in a decrease in
