Abstract
Effects of 1.0 wt.% V2O5-CuO mixture addition on the sintering behavior, phase composition and microwave dielectric properties of BiSbO4 ceramics have been investigated. BiSbO4 ceramics can be well densified below temperature about 930 °C with 1.0 wt.% V2O5-CuO mixtures addition with different ratios of CuO to V2O5. The formation of BiVO4 phase and substitution of Cu2+ can explain the decrease of sintering temperature. Dense BiSbO4 ceramics sintered at 930 °C for 2 h exhibited good microwave dielectric properties with permittivity between 19 and 20.5, Qf values between 19,000 and 40,000 GHz and temperature coefficient of resonant frequency shifting between â71.5 ppm °Câ1 and â77.8 ppm °Câ1. BiSbO4 ceramics could be a candidate for microwave application and low temperature co-fired ceramics technology.
