| 摘 要： | 采用柠檬酸sol-gel工艺合成了BaFe12O19/SiO2-B2O3-K2O微晶玻璃陶瓷, 并对其介电常数及其磁导率在100MHz～ 6 GHz 下的变化规律进行了研究。结果表明: BaFe12O19/SiO2-B2O3-K2O微晶玻璃陶瓷可以在850℃/5 h的条件下烧结而成, 其合成过程与体系中的Ba/Fe 密切相关; 其介电常数基本不随测试频率的变化而变化; 其磁导率实部随测试频率的增加而下降。

| Abstract: | BaFe12O19/SiO2-B2O3-K2O microcrystallite glass ceramics were prepared by citrate sol-gel process. The dielectric constan tand permeability dispersion were investigated in 100MHz ～ 6. 0 GH zrange. It was discovered that the synthesis temperature of BaFe12O19/SiO2-B2O3-K2O microcrystallite glass ceramics is about 850℃ and the condition such as Ba/Fe had a close effect on the syn thesis of BaFe12O19/SiO2-B2O3-K2O. It also showed that the dielectric exhib it salmo stnovariation with measuring frequency increasing. The real part of permeability decreases as the measuring frequency increasing. |
