Application of MgF2 ceramic material as ultralow dielectric microwave dielectric ceramic
The invention relates to the technical field of electronic information materials and devices thereof, in particular to application of a MgF2 ceramic material as ultralow dielectric microwave dielectric ceramic. The invention provides an application thought of using the MgF2 ceramic material as microwave dielectric ceramic, the MgF2 ceramic material has high thermal conductivity and ultralow dielectric constant (4.60-4.70) at the same time, and the problems that a ceramic-based material in an existing microwave dielectric is high in dielectric constant and polymer-based FR4 is low in thermal conductivity are solved. The dielectric constant of the MgF2 ceramic material is close to that of a commercial polymer-based FR4 plate, and the MgF2 ceramic material has ultra-low dielectric loss (Qf = 85983-103086 GHz) which is incomparable to that of the FR4 plate, and has a very important application prospect in the field of millimeter wave communication in the future.
本发明涉及电子信息材料及其器件技术领域，尤其涉及一种MgF2陶瓷材料作为超低介微波介质陶瓷的应用。本发明提供了MgF2陶瓷材料作为微波介质陶瓷的应用思路，MgF2陶瓷材料同时具备较高的热导率和超低的介电常数（4.60–4.70），解决了现有微波介质中陶瓷基材料的介电常数高、高分子基FR4热导率低的问题。而且MgF2陶瓷材料介电常数与商用的高分子基FR4板接近，同时具有FR4板不能比拟的超低介电损耗（Qf=85983–103086GHz），在未来毫米波通讯领域具有十分重大的应用前景。
