Abstract
A series BiFeO3 and BiMnO3 co-doped lead-free 0.94Bi0.5Na0.5TiO3-0.06BaTiO3 (BNBT-xBF-yBM, x = 8, 12; y = 8, 10, 12) ceramics were fabricated by solid-state method, and the detailed crystal structure, electrical properties and thermal stability were thoroughly investigated. The XRD results from the Rietveld fitting demonstrate the coexistence of Rhombohedral (R) and Tetragonal (T) phases in the ceramics at room temperature. High piezoelectric property (d33 > 160 pC/N) are obtained in BNBT-8BF-12BM and BNBT-12BF-10BM ceramics. It is of particular significance that the variations of kp in the temperature range from 25 to 70 °C is little, respectively, indicating an insensitive temperature-dependent behavior of BNBT-12BF-10BM ceramics. These results indicate the importance of simultaneous modification methods to achieve high electric properties in BNT-BT based ceramics.
