Effects of MnO2 doping on the microstructure, densification, dielectric, ferroelectric and piezoelectric properties of (Na0.5K0.5)0.935Li0.065NbO3 (NKLN) lead-free piezoelectric ceramics were investigated. On the one hand, the addition of a small amount of MnO2 has little effect on the crystalline structure, however, slightly promotes sintering and grain growth, and improves the uniformity of microstructure to a certain degree. On the other hand, MnO2 doped NKLN ceramics show hard properties in… CONTINUE READING
