Notes:
Zinc titanate ceramics having excellent dielectric properties and low sintering temperature arepromising materials for RF/microwave multilayer devices. In this paper, the ZnO-V2O5 addition wasadded to promote the sintering process in order to obtain low-temperature sintered ceramics with highquality factors. The sintering addition could also restrain ZnTiO3 phase from decomposition. Using thismethod, low-temperature sintered zinc titanate ceramics with excellent microwave dielectric propertiesof εr~ 25.3, Q×f~15200GHz, and τf ~ -16 ppm/oC were obtained at sintering temperature of 800oC. Thelow-fired mechanism, microstructure, phase formation and microwave dielectric properties of ceramicswere investigated by XRD, SEM, EDS and network analysis techniques, respectively
