| 摘 要： | 通过Li2O-B2O3-SiO(2LBS)玻璃的有效掺杂,低温液相烧结制备了16CaO-9Li2O-12Sm2O3-63TiO(2CLST)陶瓷。研究了LBS掺杂量对其烧结性能、相组成及介电性能的影响。结果表明:通过掺杂LBS,使CLST陶瓷的烧结温度由1300℃降至1000℃,且无第二相生成。随LBS掺杂量的增加,tanδ显著降低,τf趋近于零。当w(LBS)为10%时,CLST陶瓷在1000℃烧结3h获得最佳介电性能:tanδ为0.0045,τf为4×10–6/℃,虽然εr由105.0降至71.0,但仍属于高εr范围。

| Abstract: | To reduce the sintering temperature of 16CaO-9Li2O-12Sm2O3-63TiO2 (CLST) ceramics, the CLST ceramics were prepared by the traditional ceramic process at a lower sintering temperature and using Li2O-B2O3-SiO2 (LBS) glass as a liquid phase sintering assistants. The effects of LBS doping amounts on the sintering behaviours, phase compositions and dielectric properties of CLST ceramics were investigated. The results indicate that LBS glass can be used as sintering assistants to reduce the sintering temperature ... |
