| 摘 要： | 用传统工艺合成了Li2CO3掺杂的ZnO-TiO2系微波介质陶瓷,系统研究了其烧结行为、显微结构和介电性能。结果表明:掺杂质量分数1%的Li2CO3可使ZnO-TiO2陶瓷的烧结温度从1100℃降到980℃;掺杂3%Li2CO3时,在950℃保温2h烧结,于6～8GHz测试试样的介电性能为:εr约为20,Q·f约为40000GHz,τf约为–14×10–6℃–1。

| Abstract: | Li2CO3-doped ZnO-TiO2 system microwave dielectric ceramics were prepared by traditional processing. The systematic study results of sintering behavior, microstructure and dielectric properties show that sintering temperature of ZnO-TiO2 ceramic decrease from 1 100 ℃ to 980 ℃ with 1% (mass fraction) Li2CO3 addition; dielectric properties of samples with 3% Li2CO3 addition, sintered at 950 ℃ for 2 h, tested at the frequency of 6～8 GHz are: εr ≈20, Q·f ≈40 000 GHz, τf≈–14×10–6 ℃–1. |
