A series of nonstoichiometric (NaBi)0.47Ba0.06TiO3 (NBT-6BT) ceramics were prepared by the conventional solid-state method. The impact of A-site nonstoichiometry on the structural and electrical properties of the prepared ceramics was investigated. The room temperature diffraction patterns and Raman spectra revealed the coexistence of the Cc and P4bm phases for all samples. The experimental results in the present work showed that a deficiency in the Bi3+ and Na+ contents could lead to a transformation from the Cc to P4bm phase in addition to a variation in the piezoelectric coefficient d33 with the Cc phase fraction. Favorable thermostability for the piezoelectric properties of the ceramics was observed by testing the depolarization temperature (Td). Among them, the d33 of the N0.32B0.32T-6BT ceramics still had a value of 23 pC/N at 160 ℃. These results showed that a deficiency in the Na+ and Bi3+ contents can significantly enhance Td and extend the temperature region for the application of NBT-6BT ceramics.
