摘要
Li2Ti1-x(Zn1/3Nb2/3)(x)O-3 (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 x 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 epsilon(r)=20.5, Q x f=75,257 GHz, and tau(f)=15.4 ppm/degrees C could be obtained when x=0.2. (C) 2012 Elsevier Ltd and Techna Group S.r.l.
