摘要：

Novel glass-free low temperature firing microwave dielectric ceramics Li2CeO3 with high Q prepared through a conventional solid-state reaction method had been investigated. All the specimens in this paper have sintering temperature lower than 750 degrees C. XRD studies revealed single cubic phase. The microwave dielectric properties were correlated with the sintering conditions. At 720 degrees C/4h, Li2CeO3 ceramics possessed the excellent microwave dielectric properties of epsilon(r)=15.8, Qxf=143700 (GHz), and (f) =-123ppm/degrees C. Li2CeO3 ceramics could be excellent candidates for glass-free low-temperature co-fired ceramics substrates.
