MgTiO3/TiO2/MgTiO3: An ultrahigh-Q and temperature-stable microwave dielectric ceramic through cofired trilayer architecture
Source abstract
Abstract
Abstract A cofired trilayer ceramic architecture showing as MgTiO3/TiO2/MgTiO3 was designed to realize temperature-stable and ultrahigh-Q microwave dielectrics in the typical MgTiO3-TiO2 system. The effects of TiO2 content on the microwave dielectric properties of cofired trilayer ceramics were studied. Through the design of cofired trilayer architecture, the chemical reactions between MgTiO3 and TiO2 were limited within a narrow region of MgTiO3/TiO2 interfaces (~ 15 µm in width), which could be beneficial for optimizing the microwave dielectric properties. Excellent characteristics of er ~ 18.38, Q×f value ~ 169,900 GHz and τf ~ − 1 ppm/°C were gained for the MgTiO3/TiO2/MgTiO3 ceramic architectures stacked with 1.63 vol% TiO2. The current work could serve as new strategies to develop high-performance dielectric resonators and multilayers for 5G wireless communication applications.
