Abstract

Through an analysis of the temperature stability of (K _0.5Na _0.5) NbO ₃ (KNN) based ceramics and KNN solid solutions, we propose a method to enhance the temperature stability of KNN materials. These materials are valuable for their piezoelectric properties. To verify the feasibility of this method, 0.9 (K _1-xNa _x) NbO ₃-0.06LiNbO ₃-0.04CaTiO ₃(KNLN-CaTiO ₃) ceramics were designed, and their structure and properties were studied. The results show that KNLN-CaTiO ₃(x = 0.54) ceramics have a good temperature stability over a wide temperature range (25-320°C). Also, they have good piezoelectric properties (d ₃₃=152 pC/N in x=0.54). This result confirms the feasibility of our proposed solution for improving the piezoelectric properties of KNN-based ceramics that have poor temperature stability.
