| 摘 要： | 采用传统固相反应法制作(Ni1/3Nb2/3)0.7Ti0.3O2微波陶瓷,研究了CuO掺杂对所制陶瓷低温烧结性能、微观结构、相构成及微波介电性能的影响。结果表明,掺杂少量的CuO就能显著降低(Ni1/3Nb2/3)0.7Ti0.3O2陶瓷的烧结温度,且能改善陶瓷τf。当CuO掺杂量(质量分数)为1.0%时,(Ni1/3Nb2/3)0.7Ti0.3O2在950℃烧结,显示出良好的微波介电性能:εr=67.65,Q·f=3708GHz,τf=14.3×10-6/℃。

| Abstract: | The(Ni1/3Nb2/3)0.7Ti0.3O2 microwave ceramics were prepared by the conventional solid state reaction process.The low singtering behavior,microstructure,phase composition and microwave dielectric properties of prepared ceramics were studied.The results show that a small amount of CuO addition to(Ni1/3Nb2/3)0.7Ti0.3O2 ceramics decreases the sintering temperature effectively.Also,the τf is optimized by CuO doping.Especially,the 1.0%(mass fraction) CuO-doped(Ni1/3Nb2/3)0.7Ti0.3O2 ceramics are sintered at 950 ℃ with good microwave dielectric properties of εr = 67.65,Q?f = 3 708 GHz,and τf = 14.3×10-6 /℃. |
