Abstract

V2O5 was added to ceramics of nominal composition Zn1.8SiO3.8 (ZS) in order to decrease their sintering temperature for application to low-temperature cofired ceramic devices. For the specimens sintered at 875°C, a dense microstructure was developed when the V2O5 content exceeded 9.0 mol% due to the presence of the liquid phase containing SiO2 and V2O5. The microwave dielectric properties of the ZS ceramics were influenced by the V 2O5 content. Good microwave dielectric properties of Q×f=17 500 GHz, εr=7.3, and τf=-28 ppm/°C were obtained from the specimen containing 12.0 mol% V 2O5 sintered at 875°C for 2 h.
