- Abstract
The influences of V2O5 and CuO additives on the sintering behavior and microwave dielectric properties of BiNbO4 ceramics were investigated. The V2O5 and CuO additives lowered the sintering temperature of BiNbO4 ceramics to the range 875 °C–935 °C. All BiNbO4 compounds with additives had the orthorhombic structure. The dielectric constant εr was not significantly changed, while the unloaded Q value was affected with additives. The Qf value was found to be a function of the sintering temperatures and the amount of additives. It varied from 4500 to 15800 (GHz) and 1000 to 8000 (GHz) with additives V2O5 and CuO, respectively. The τ f values were increased in positive values with V2O5 doped, while decreased in negative values with CuO addition. V2O5 and CuO additives effectively improved the densification and dielectric properties of BiNbO4 ceramics. The correlation between the microstructure and the Qf value was observed with different additives.
