| 摘 要： | 利用X射线衍射、扫描电子显微镜等手段研究了添加La2O3-B2O3玻璃作为烧结助剂的Zn0.5Ti0.5NbO4微波介质陶瓷在低温烧结过程中的结构及微波介电性能变化。实验结果表明,适当的La2O3-B2O3玻璃添加不会影响Zn0.5Ti0.5NbO4陶瓷的相组成。添加质量分数2%的La2O3-B2O3烧结助剂有助于在烧结过程中形成液相,液相能有效加速Zn0.5Ti0.5NbO4陶瓷的低温烧结过程,实现Zn0.5Ti0.5NbO4陶瓷的致密化。在875℃烧结时,添加质量分数2%La2O3-B2O3玻璃的Zn0.5Ti0.5NbO4陶瓷具有优异的微波介电性能:εr=33.91,Q×f=16579 GHz(f=6.1 GHz),τf=-68.54×10-6/℃。

| Abstract: | Here the structure and dielectric properties of Zn0.5Ti0.5NbO4 microwave dielectric ceramics with La2O3-B2O3 sintering additives were studied by X-ray diffraction and scanning electron microscope.The results show that small amount of La2O3-B2O3 additives do not alter the phase composition of Zn0.5Ti0.5NbO4 ceramics.La2O3-B2O3 additive of 2%is beneficial to form liquid phase,which can accelerate the low temperature sintering process of the Zn0.5Ti0.5NbO4 ceramics to realize densification.Excellent microwave dielectric parameters were obtained for the Zn0.5Ti05NbO4 ceramics with 2%La2O3-B2O3 at sintering temperature of 875℃,such thatεr=33.91,Q×f=16579 GHz(f=6.1 GHz),τf=-68.54×10-6/℃. |
