摘要：

超低温烧结微波介质陶瓷作为无源集成技术的主要介质材料，可广泛应用于无线通讯、可穿戴电子、物联网和全球定位系统等领域，其相关研究具有重要的应用价值和理论指导意义，是目前功能材料领域的研究热点之一。本文综合介绍了超低温烧结微波介质陶瓷材料的应用背景和主要的材料体系，以及主要材料体系的介电性能和优缺点，探讨了材料组分、介电常数、Qf值、频率温度系数之间的关系，阐述了超低温烧结陶瓷材料的性能调控手段，并指出了今后超低温烧结微波介质陶瓷材料的主要发展前景和研究方向。钼酸盐基超低温烧结陶瓷兼具超低烧结温度、系列化介电常数和低损耗等优点，有望实现在超低温共烧技术中的应用。离子取代和多相复合是有效调控材料微波介电性能的方法，使材料更利于应用。

The ultra-low temperature co-fired ceramics (ULTCC) can be widely used in various fields like wireless communication, wearable electronics, internet and global positioning system, etc. Studies on the theories and practical application of these dielectric materials have attracted much attention, especially for microwave dielectric ceramics. This review introduced the development of ultra-low temperature co-fired ceramics for microwave applications. The microwave dielectric properties and the advantages/disadvantages of the materials were also represented. The relationships among the material composition, dielectric constant, Qf value and temperature coefficient of resonance frequency were discussed. The performance tailoring and controlling of the ultra-low temperature co-fired ceramics were analyzed. Further studies on this aspect were prospected. The molybdate based ultra-low temperature sintering ceramics with ultra-low sintering temperatures, series of dielectric constants and low dielectric loss could be potentially used in ultra-low temperature co-firing technology. The ionic substitution and multiphase composite both are effective ways to regulate the microwave dielectric properties for the use of the materials.
