Abstract

Lead free materials 0.95(K_0.5Na_0.5)NbO ₃-0.05LiSbO₃ modified by CaTiO₃ (CT) (1-3wt%) have been synthesized by conventional sintering. All samples exhibited pure perovskite phase with a tetragonal structure at room temperature. The Curie temperature was found to decrease with increasing CT addition in KNN-LS ceramics, while the orthorhombic to tetragaonl polymorphic phase transition was found to shift further downward from room temperature to lower than -50°C, expanding the temperature usage range. The piezoelectric coefficient d31 and electroemchanical coupling factor k₃₁ for CT (1wt%) modified KNN-LS materials were found to be on the order of -90pC/N and -28.5% at room temperature, respectively, comparable to those values of pure KNN-LS. Together with its broadened temperature usage range, makes the CT modified materials promising candidates for sensor and transducer applications.
