Piezoelectricity in excess of 30 pC N<sup>−1</sup> with a high Curie temperature of 950 °C in strongly textured CaBi<sub>2</sub>Nb<sub>2</sub>O<sub>9</sub> ceramics
The Na/Sm co-doped CaBi 2 Nb 2 O 9 textured ceramics with a high texture degree of 95–98% were successfully prepared by improved grain growth method, achieving the highest piezoelectric coefficient ( d 33 > 30 pC N −1 ) in the CaBi 2 Nb 2 O 9 systems.
