Effects of CuO-V2O5-Bi2O3 Additions on the Microstructure and Microwave Dielectric Properties of 0.42ZnNb2O6-0.58TiO2 Ceramics
The effects of additions on the microstructure and microwave dielectric properties of 0.42ZnNb2O6-0.58TiO2 (ZNT) ceramics were investigated systematically. The sintering temperature of ZNT ceramics doped with different amounts of CuO, Bi2O3 and V2O5 can be effectively reduced. The phase of doped samples was studied compared to the undoped ZNT ceramics. For densified ZNT ceramics with the increasing amount of dopant CuO-Bi2O3-V2O5, the dielectric constants (εr) of densified samples ranges from 38 to 42, the Q×f values decrease evidently and ranges from 13300 GHz to 5000 GHz and the τf values are shifted toward negative.
