| 摘 要： | 采用传统压电陶瓷工艺制备了(1-x)B i0.5(Na0.8K0.2)0.5TiO3-xNaSbO3无铅压电陶瓷,利用XRD、SEM等测试技术表征了陶瓷的晶相结构和表面形貌,利用一些电学仪器测试了其介电和压电性能.结果表明,该体系陶瓷具有单相钙钛矿结构,适量的NaSbO3掺杂可以提高该陶瓷的致密性.在室温下,当掺杂量为0.5%时,该体系表现出较好的压电性能:压电常数d33和机电耦合系数kp分别达到107pC/N和0.209;当掺杂量为0.7%时,εr和tanδ分别为1 551和0.05.

| Abstract: | (1-x)Bi0.5(Na0.8K0.2)0.5TiO3-xNaSbO3 lead-free piezoceramics were prepared by conventional mixed-oxide method.Microcosmic structure and shape were studied by x-ray diffraction and scanning electron microscope.Piezoelectrical and dielectrical properties were measured by digital electron instruments.The main conclusions obtained from above research were as follows: all the samples were single perovskite structure.appropriate amount of NaSbO3 could improve compactness of the ceramics.When NaSbO3 were 0.5%,the ... |
