摘要: 本文采用循环搅拌–高能球磨复合型陶瓷粉体制备工艺及固相反应法制备了高性能0.7CaTiO3-0.3NdAlO3介质陶瓷，并分析了0.7CaTiO3-0.3NdAlO3介质陶瓷的物相组成和微观结构及其微波元器件的介电性能。研究表明，循环搅拌–高能球磨复合型工艺制0.7CaTiO3-0.3NdAlO3介质陶瓷的物相结构为单相正交钙钛矿晶型；0.7CaTiO3-0.3NdAlO3介质陶瓷微波谐振器及其组装的腔体滤波器的“温漂”指标均满足通讯基站用微波谐振元件和腔体滤波器的技术要求。
Abstract: The high performance 0.7CaTiO3-0.3NdAlO3 dielectric ceramics were prepared by the composite process of ceramic powders by cyclic mixing-high energy ball milling and solid state reaction method. The phase composition, microstructure of the 0.7CaTiO3-0.3NdAlO3 dielectric ceramics and dielectric properties of its microwave devices were analyzed. The results indicated that 0.7CaTiO3-0.3NdAlO3 dielectric ceramics are single-phase orthogonal perovskite-structure. The temperature drift index of the microwave resonator manufactured by 0.7CaTiO3-0.3NdAlO3 die-lectric ceramics and the assembled cavity filter are consistent with the technical requirements of microwave resonant components and cavity filters for communication base station.
