摘要:Piezoelectric temperature stability is often a critical issue for the (K,Na)NbO3-based lead-free ceramics when used in some technical products like filters and ultrasonic devices. In this letter, we report the excellent piezoelectric performance of a dense 0.96(K0.48Na0.52)(Nb0.96Sb0.04)O3–0.03BaZrO3–0.01(Bi0.50Na0.50)ZrO3 ceramic, which shows high piezoelectric coefficient d33 = 300 pC/N and large electromechanical coupling factors kp = 0.56, k33 = 0.69 at room temperature and weak piezoelectric temperature dependences in the common usage temperature range between −30 °C and 100 °C. It seems that the obtained excellent piezoelectric performance associates closely with the diffused R-O phase transition and the stable piezoelectric nature of orthorhombic phase.
