Abstract

Li2Ti1−x(Zn1/3Nb2/3)xO3 (0≤x≤0.5) ceramics were prepared by a solid state ceramic route, and the phase purity, microstructure, and microwave dielectric properties were investigated. The XRD results suggest the formation of solid solutions for all studied compositions (0≤x≤5). The dielectric properties are strongly dependent on the compositions, the densifications and the microstructures of the samples. The Q×f value increases with x up to x=0.2 and then decreases with the further increase of x. The best microwave dielectric properties of εr=20.5, Q×f =75,257 GHz, and τf =15.4 ppm/°C could be obtained when x=0.2.
