Zirconium borate microwave dielectric ceramic material and preparation method thereof
The invention provides a zirconium borate microwave dielectric ceramic material and a preparation method thereof, and belongs to the technical field of dielectric ceramics. Zirconium borate ceramic powder is prepared in a pre-sintering mode, then low-temperature pressing sintering is carried out by utilizing a cold sintering process, and finally, the compactness of a zirconium borate microwave dielectric ceramic blank is improved by utilizing annealing treatment, so that the sintering temperature is greatly reduced, and the sintering time is greatly shortened. The zirconium borate microwave dielectric ceramic material has a small dielectric constant, a near-zero temperature coefficient of resonance frequency and a high quality factor, so that the zirconium borate microwave dielectric ceramic material has good dielectric properties, and is high in signal transmission efficiency and good in temperature stability of signal transmission after being used in the field of communication. The result of the embodiment shows that the dielectric constant of the zirconium borate microwave dielectric ceramic material is 5.23-6.63, the temperature coefficient of resonance frequency is 12.83 ppm/DEG C, and the quality factor is 6455-19375.
本发明提供了一种硼酸锆盐微波介质陶瓷材料及其制备方法，属于介质陶瓷技术领域。本发明通过预烧结的方式制备硼酸锆盐陶瓷粉体，然后利用冷烧结工艺进行低温压制烧结，最后利用退火处理来提高硼酸锆盐微波介质陶瓷坯体的致密性，从而在大幅度降低了烧结温度的情况下，使硼酸锆盐微波介质陶瓷材料具有介电常数小、近零的谐振频率温度系数和高品质因数，进而使硼酸锆盐微波介质陶瓷材料介电性能好，用于通讯领域后信号传输效率高且信号传输的温度稳定性好。实施例的结果显示，本发明得到的硼酸锆盐微波介质陶瓷材料的介电常数为5.23～6.63，谐振频率温度系数为12.83ppm/℃，品质因数为6455～19375。
