Bi0.5Na0.5TiO3-Ba(Al0.5Sb0.5)O3陶瓷的压电、铁电特性及场致应变效应
Piezoelectric and ferroelectric and electric-field induced strain properties in Bi0.5Na0.5TiO3-Ba(Al0.5Ta0.5)O3ceramics
摘要
Abstract
The (1–x)Bi0.5Na0.5TiO3-xBa(Al0.5Sb0.5)O3(x=0.03–0.05) piezoelectric ceramics were prepared by conventional ceramic technique. The effects of Ba(Al0.5Sb0.5)O3content on the dielectric, piezoelectric and ferroelectric properties, and electric-field induced strain of Bi0.5Na0.5TiO3(BNT) ceramics were investigated. The results indicate that there exists a phase transition from polar ferroelectric phase to non-polar non-ferroelectric phase with the content of second member Ba(Al0.5Sb0.5)O3increasing. Due to the multiphase coexistence, the composition with x=0.035 exhibits the optimal properties: d33=99 pC/N, Smax=0.27%, kp=20.1%, kt=30.4%, d*33=386 pm/V.关键词
