Abstract

0.6mol% V2O5-doping 0.996(0.95Na0.5K0.5NbO3-0.05LiSbO3)-0.004FeBiO3 ((KNN-LS- BF)-V2O5) piezoelectric ceramics were synthesized by the solid-state reaction process, and the influence of sintering time on structure and properties of (KNN-LS-BF)-V2O5 ceramics were studied. It was found that all the samples sintered for various time are perovskite structure mixed with orthorhombic symmetry phase and tetragonal phase, but the sintering time has significant influence on the crystalline and properties. When the sintering time increases from 2 hours to 6 hours, the grain of (KNN-LS-BF)-V2O5 ceramics becomes more homogeneous and more tight-arrangement. The results revealed that the longer sintering time than 4 hours is beneficial for improving partial properties, such as d33, tan and Qm, but is adverse to r and kp, the (KNN-LS-BF)-V2O5 ceramics with optimum properties can be synthesized for 6 hours at 1080øC.
