摘要：
Zinc titanate ceramics having excellent dielectric properties and low sintering temperature are promising materials for RF/microwave multilayer devices. In this paper, the ZnO-V2O5 addition was added to promote the sintering process in order to obtain low-temperature sintered ceramics with high quality factors. The sintering addition could also restrain ZnTiO3 phase front decomposition. Using this method, low-temperature sintered zinc titanate ceramics with excellent microwave dielectric properties of epsilon(l) similar to 25.3, Q x f similar to 15200GHz, and tau(f) similar to -16 ppm/degrees C were obtained at sintering temperature of 800 degrees C. The low-fired mechanism, microstructure, phase formation and microwave dielectric properties of ceramics were investigated by XRD, SEM, EDS and network analysis techniques, respectively.
