Abstract
The invention discloses a high-quality-factor microwave dielectric ceramic material and a preparation method thereof. A structural expression formula of the ceramic material is (1-y)Ca2Na6Al6Si6O24(XO4)2-yTiO2, wherein y is greater than or equal to 0.07 and less than or equal to 0.16, and X is one of S, Mo and W. The material is prepared through a traditional high-temperature solid-phase synthesismethod; a small amount of dispersant is added in a secondary ball milling process, and then the material is subjected to ultrasonic vibration under a hot environment, so that powder particles of a sample are not easy to agglomerate. The material prepared by the preparation method is sintered well at 1075 DEG C to 1125 DEG C and has the characteristics that the dielectric constant is 8.5 to 10.6,the quality factor Qf value reaches 78600GHz to 117000GHz and the resonant frequency temperature coefficient is small. Meanwhile, the invention discloses Ca2Na6Al6Si6O24(XO4)2 (X is one of S, Mo and W) ceramic with a hauynite structure for the first time, and the ceramic has good microwave dielectric performance.
