摘要
以BaCO3、SnO2和TiO2等为粗料,以Y2O3为掺杂剂,采用固态反应烧结技术制备了BaSnxTi1-xO3(BTS)陶瓷。结果表明,Y 元素的掺入并没有明显改变钛酸钡锡的晶格结构,也没有出现新的相,但由于 Y3+ 离子的掺入,随着 Y3+ 掺入量的增加,衍射峰的位置发生了变化。有趣的是,样品的居里温度从 35 o C(空白样品)升高到 50 o C(0.05 mol%),然后随着掺杂量的不断增加,居里温度向低温移动,这与 Y3+ 离子的掺杂机理有关。掺杂 Y2O3 后,样品的介电损耗降低,特别是当掺杂量达到 0.10 mol% 时,样品的介电损耗表现出优异的温度稳定性,使其成为应用的上佳候选材料。
Microstructure, dielectric properties and phase transition of Y2O3-doped barium tin titanate ceramics
BaCO3, SnO2 and TiO2 et al were used as crude materials, and Y2O3 was used as dopant, BaSnxTi1-xO3 (BTS) ceramics were prepared by solid-state reaction sintering technology. The results show that the doping of Y element does not change the lattice structure of barium tin titanate obviously, and there is no new phase, however, owing to the Y3+ ion doping, the diffraction peak position is changed as the Y3+ doping amount increasing. Interestingly, Curie temperature of the sample increased from 35 o C (blank sample) to 50 o C (0.05 mol%), and then the Curie temperature moved to low temperature as the doping amount increased continuously, which is related to the doping mechanism of Y3+ ion. After doping Y2O3, the dielectric loss of the samples decreases, especially when the doping amount reaches 0.10 mol%, the specimen shows excellent temperature stability of dielectric loss, making it superior candidates for applications.
