Influence of Sintering Temperature on KNN-BF-LS Piezoelectric Ceramic

Abstract:

In this paper, (K_0.5Na_0.53)_0.932Nb_0.932O₃-0.008BF-0.06LS (abbreviated as KNN-BF-LS) piezoelectric ceramic was prepared by sol-gel method. Structure and properties of ceramics were analyzed.Through analysis of the results, when sintering temperature is 1080°C, ceramic has good perovskite structure. At this temperature, grain size is more uniform, and structure is the most dense. Piezoelectric constant d₃₃, electromechanical coupling coefficient Kp, dielectric constant ε_r reached the maximum value, respectively, 113pC/N, 0.33, 591. Dielectric loss tanδ reached the minimum 0.11.
