摘要
Abstract
Lead-free piezoelectric ceramics (1-x)(K0.5 Na0.5 )NbO3-xCaZrO3 (KNN-CZ)were prepared by traditional ce-ramics process.The phase structure of ceramics was analyzed.Results show that all specimens exhibit a pure perovskite structure and the phase structure at room temperature changes from orthorhombic to tetragonal phase,then to cubic phase with increasing amount of CaZrO3 .The effect of CaZrO3 content on piezoelectric properties was investigated in details. When the content of CaZrO3 is 0.05 mol,d33 and kp reach their maxmum.In addition,good temperature stability of electri-cal properties is obtained in (1-x)KNN-xCZ (x=0.05)ceramics These results indicate that(1-x)KNN-xCZ (x=0. 05)ceramic is a promising lead-free piezoelectric candidate materials.关键词
