Synthesis and Microwave Dielectric Properties of Novel Temperature Stable High Q, Li2ATi3O8 (A=Mg, Zn) Ceramics
Abstract:Li2ATi3O8 (A=Mg, Zn) ceramics are prepared by the conventional solid-state ceramic route, and the phase purity, microstructure, and microwave dielectric properties are investigated. Li2MgTi3O8 ceramics show r=27.20, Qu×f=42 000 GHz, and f=(+) 3.2 ppm/°C, and Li2ZnTi3O8 ceramics have r=25.6, Qu×f=72 000 GHz, and f=(−) 11.2 ppm/°C, respectively, when sintered at 1075°C/4 h.
