Abstract Tri-layered Zn3Nb2O8–TiO2–Zn3Nb2O8 ceramic with high temperature stability are initially fabricated. On the basis of X-ray diffraction, Raman spectra and HFSS (High Frequency Structure Simulator) simulation, a reasonable parallel mode is put forward, then the transition layer at the heterogeneous interface is considered to be crucial to the microwave response in this system, and the theoretical feasibility of layer-cofired microwave dielectric ceramics is verified. Contrasting to the random distribution type Zn3Nb2O8–TiO2, this structure can substantially reduce the amount of TiO2 and achieve an eightfold increase in Qf value, which is conducive to produce the new generation microwave passive devices.

层共烧 Zn3Nb2O8–TiO2–Zn3Nb2O8 陶瓷结构中的微波响应机制

摘要 初步制备了具有高温稳定性的三层Zn3Nb2O8-TiO2-Zn3Nb2O8陶瓷。在X射线衍射、拉曼光谱和HFSS（高频结构模拟器）模拟的基础上，提出了合理的并行模式，然后认为异质界面处的过渡层对该系统的微波响应至关重要，验证了层状共烧微波介质陶瓷的理论可行性。与随机分布型 Zn3Nb2O8-TiO2 相比，这种结构可以大幅度减少 TiO2 的用量，Qf 值提高 8 倍，有利于生产新一代微波无源器件。
