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)­K1–w Na w Nb1–z Sb z O3–...
