Effect of ZnO-V₂O₅ Co-Doping on Phase Stability and Microwave Dielectric Properties of ZnTiO₃ Ceramics

Abstract:

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 from decomposition. Using this method, low-temperature sintered zinc titanate ceramics with excellent microwave dielectric properties of εr~ 25.3, Q×f~15200GHz, and τf ~ -16 ppm/oC were obtained at sintering temperature of 800oC. The low-fired mechanism, microstructure, phase formation and microwave dielectric properties of ceramics were investigated by XRD, SEM, EDS and network analysis techniques, respectively.
