| 摘 要： | 采用传统的陶瓷烧结技术,通过添加0.15%(摩尔分数)CeO2,在1120℃烧结2h,成功制备了新型无铅压电陶瓷Ba0.9 Ca0.1 Ti1-x Snx O3,并且检测了陶瓷样品的微结构和电性能.XRD显示所有陶瓷样品均具有纯的钙钛矿结构,在室温下为典型的四方相,SEM显示适量添加锡离子可以提高陶瓷致密性.在室温下,锡离子改性的BaTiO3基压电陶瓷在x=0.02处显示了优异的压电、介电和铁电性能(d33=276 pC/N,kp=46%,εr=3678,tanδ=2.4%,Pr=18.2μC/cm2,EC=1.12 kV/mm).这些优异的检测结果证实适当添加锡离子能改善BaT iO3基压电陶瓷的电性能.

| Abstract: | New lead-freepiezoelectricceramicsBa0.9Ca0.1Ti1 - xSnxO3 with0.15% (molefraction)CeO2doping wereprepared via the conventional sintering technique at 1120 ℃ for 2 h ,and the products' microstructure and electrical properties were investigated . X-ray diffraction indicates that all the ceramics possess a pure perovskite structure with typical tetragonal symmetry ,SEM micro-graphs suggest that the appropriate addition amount of Sn can enhance the compactness .The Sn-modified BaTiO3-based ceramics exhibit an optimum piezoelectric ,dielectric and ferroelectric properties (d33 =276 pC/N ,kp =46% ,εr =3678 ,tanδ=2 .4% , Pr =18 .2 μC/cm2 ,EC =1 .12 kV/mm) at room temperature while x=0 .02 .These excellent results demonstrate that appropriate amount of Sn can further improve the electrical properties of BaTiO3-based piezoelectric ceramics . |
