| 摘 要： | 采用传统的电子陶瓷制备工艺制备了一系列0.93Bi0.5Na0.5TiO3-0.07(Ba1-xSrx)TiO3(简写为BNBST100x;x=0.02,0.04,0.06,0.08,0.10)陶瓷,研究了陶瓷的结构、介电、压电性能变化特征.XRD分析表明,陶瓷样品均形成了单一的钙钛矿结构固溶体.陶瓷的介电、压电性能受Sr含量的影响显著.所有陶瓷样品表现出弥散相变特征.BNBST陶瓷的压电常数随着Sr含量的增加表现出先增大后减少的趋势.同时,当Sr含量为4 mol%时,压电常数(d33达到最大,分别为139.8 pC/N.

| Abstract: | (Bi0.5Na0.5)0.93(Ba1-xSx)0.07TiO3 (abbreviated to BNBST100x,x=0.02, 0.04, 0.06, 0.08, 0.10) lead-free piezoelectric ceramics were prepared by the conventional ceramic technique. Crystal structure, dielectric and piezoelectric properties of the ceramics were investigated. X-ray diffraction (XRD) analysis showed that all the ceramics formed single-phase solid solutions with perovskite structure. The dielectric and piezoelectric properties of the ceramics were affected obviously by the content of Sr. The ceram... |
