Bismuth layer-structured ferroelectric ceramics of (1−x)Na0.5Bi2.5Nb2O9xLiNbO3 (NBN–LN, 0≤x≤0.2) were synthesized by a traditional solid-state reaction. The effects of LN addition on the microstructure and electrical properties of ceramics were studied carefully. It was found that the ceramics with x≤0.10 have a bismuth oxide layered structure. With the increasing of LN addition, the mechanical quality factor Qm firstly increases, and then decreases with a maximum value of 4820 at x=0.02. The Curie temperature Tc increases gradually and the electrical properties of NBN-based ceramics are improved significantly by the addition of LN. The piezoelectric constant d33, dielectric loss tan , Curie temperature Tc, and remanent polarization Pr of 0.90Na0.5Bi2.5Nb2O9–0.10LiNbO3 ceramics were found to be 21 pC/N, 0.16%, 789°C, and 7.37 C/cm2, respectively. Thermal annealing and aging studies indicate that the NBN–LN system possesses stable piezoelectric properties, demonstrating that the NBN–LN ceramics are the promising candidates for high-temperature applications.
