Microwave dielectric ceramic with low dielectric constant and low loss and preparation method thereof
The invention discloses a microwave dielectric ceramic with low dielectric constant and low loss and a preparation method thereof, the chemical composition expression of the microwave dielectric ceramic is CaLaAl3O7, and the microwave dielectric ceramic has low dielectric constant (5.8-6.3), low loss (7.2 * 10 <-4 >) and negative temperature coefficient of resonance frequency (-37 to-31 ppm/DEG C). The microwave dielectric ceramic has low dielectric constant and lower loss, is an ideal candidate material of low-dielectric microwave ceramics in the field of wireless communication, is prepared by adopting a traditional solid-phase reaction method, is mature in process, can be industrially produced, is high in reproducibility and can be used for synthesizing a stable pure phase.
本发明公开了一种低介电常数低损耗的微波介质陶瓷及其制备方法，本发明的微波介质陶瓷的化学组成表达式为CaLaAl3O7，其具有低介电常数(5.8～6.3)，低损耗(7.2×10‑4)以及负的谐振频率温度系数(‑37～‑31ppm/℃)。本发明的微波介质陶瓷具有低介电常数与较低损耗，是无线通信领域低介电微波陶瓷的理想候选材料，同时采用传统固相反应法制备，工艺成熟且可工业化生产，复现性强且能合成稳定的纯相。
