Medium dielectric constant microwave dielectric ceramic and preparation method thereof
The invention belongs to the field of electronic ceramics and manufacturing thereof, and relates to a medium-dielectric-constant microwave dielectric ceramic material and a preparation method thereof. The chemical formula of the microwave dielectric ceramic with the medium dielectric constant provided by the invention is LiCuTa3O9, the sintering temperature is 1200-1300 DEG C, the dielectric constant is adjustable in a range of 20-35, and the Q * f value can reach 12745 GHz at most. The LiCuTa3O9 ceramic is prepared through a solid-phase reaction method, and compared with existing commercial tantalate ceramic, the LiCuTa3O9 ceramic provided by the invention is short in heat preservation time at the sintering temperature and low in preparation energy consumption.
本发明属于电子陶瓷及其制造领域，涉及一种中等介电常数微波介电陶瓷材料及其制备方法。本发明提供的中等介电常数微波介电陶瓷的化学式为LiCuTa3O9，添烧结温度为1200～1300℃，介电常数在20～35范围内可调，Q×f值最高可达到12745GHz。所述LiCuTa3O9陶瓷通过固相反应法制得，相较于目前商用的钽酸盐陶瓷，本发明提供LiCuTa3O9陶瓷在烧结温度下保温时间短，制备能耗低。
