双稀土掺杂BCST陶瓷的研制及其性能结构的研究
Preparation and Structure and Dielectric properties of BCST Doped with Pr and Nd
摘要
Abstract
Sol-gel method was used to synthesize BCST( Ba0 62Ca0 08Sr0 3Ti03) powder. And then nanometer-sized BCST: 0. 001Pr6On ?xNd2O3 series powders and ceramics were prepared by dopingPr6On andNd2O3 through solid state doping method. The phases of the powders were tested by X-ray Diffraction, the patterns of the; ceramics were observed by SEM, and the dielectric properties were measured by Dielectric Frequency and Temperature Spectrum Analyzer. The results showed that the BCST^O. 00Pr6Ou ·0.002Nd2O3 powder was found to be tetragonal phase and nanometer-size; with the increase of the doping quantity ofNd2O3 the grain size of the BCST: 0. 001Pr6Ou ? xNd2O3 series ceramics became smaller and then larger gradually; the ceramic had the highest dielectric constant and the lowest dielectric loss at room temperature when x =0. 002; the dielectric constant of each ceramic sample became higher with the increase of the sinter temperature.关键词
