Heterogeneity Challenges in Multiple-Element-Modified Lead-Free Piezoelectric Ceramics. [PDF]
Materials (Basel), 2019 We report on a heterogeneity study, down to the atomic scale, on a representative multiple-element-modified ceramic based on potassium sodium niobate (KNN): 0.95(Na0.49K0.49Li0.02)(Nb0.8Ta0.2)O3–0.05CaZrO3 with 2 wt % MnO2. We show that different routes for incorporating the MnO2 (either before or after the calcination step) affect the phase ...

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
