To achieve high piezoelectric activity and a wide sintering temperature range, the ceramic system concerning (1 - x)(K0.48Na0.52)(Nb0.96Sb0.04)O-3-x[Bi-0.5(Na0.7Ag0.3)(0.5)](0.90) Zn0.10ZrO3 was designed, and the rhombohedral-tetragonal (R-T) phase boundary can drive a high d(33). Phase transition characteristics as well as their effects on the electrical properties were investigated systematically. The R-T coexistence phase boundary (0.04 <= x <= 0.05) can be driven via modification with BNAZZ, and has been confirmed by XRD and temperature-dependent dielectric constants as well as Raman analysis, and the ceramics possess enhanced piezoelectric properties (d(33) similar to 425 pC N-1 and k(p) similar to 0.43) and a high unipolar strain (similar to 0.3%). In addition, a wide sintering temperature range of 1050-1080 degrees C can warrant a large d(33) of 400-430 pC N-1, which can benefit practical applications. As a result, the addition of BNAZZ is an effective method to improve the electrical properties (piezoelectricity and strain) and sintering behavior of potassium-sodium niobate ceramics.
