Sb3+和Ba2+共掺杂锆钛酸铅压电陶瓷的制备与表征
Preparation and characterization of Ba2+and Sb3+co-doped PZT piezoelectric ceramics
摘要
Abstract
Sb3+and Ba3+co-doped lead zirconate titanate(PZT)ceramics were prepared by solid-phase sintering method using antimonous oxide and barium carbonate as doped raw materials.The phase,micro-morphology and electromechanical properties of the medium were studied by XRD,SEM,automatic component analyzer,quasi-static D33 measuring instrument and precision impedance analyzer.The results showed that Sb3+and Ba2+co-doped lead zirconate titanate ceramics had better compactness.When the mass fraction of doped Sb2O3 was 1％and doped BaO was 2％,the electromechanical property was significantly improved.The relative dielectric constant was 1 854,the piezoelectric coefficient was 439.6 pC/N,the electromechanical coupling coefficient was 66％,and the Curie temperature was reduced from 398 to 380 ℃.The high piezoelectric constant is conducive to improving the receiving and transmitting sensitivity of the electronic components prepared by PZT.关键词
