Giant Piezoelectricity and High Curie Temperature in Nanostructured Alkali Niobate Lead-Free Piezoceramics through Phase Coexistence

Because of growing environmental concerns, the development of lead-free piezoelectric materials with enhanced properties has become of great interest. Here, we report a giant piezoelectric coefficient ( d 33 ) of 550 pC/N and a high Curie temperature ( T C ) of 237 °C in (1– x – y )K 1– w Na w Nb 1–... View More
