Abstract

Microstructures and microwave dielectric properties of 0.5Ba(Mg_1/3Nb_2/3)O₃-0.5Ba(Ni_1/3Nb_2/3)O₃ ceramics with x wt% CuO−x wt% MnO₂ additions (x=0.25–1) prepared by conventional solid-state route were investigated. It is found that low level-doping of CuO-MnO₂ can significantly improve the density of the specimens and their microwave dielectric properties. The relative density of 0.5Ba(Mg_1/3Nb_2/3)O₃-0.5Ba(Ni_1/3Nb_2/3)O₃ ceramics can be increased by 95% sintering at 1 330 °C due to the liquid phase effect. The second phase is not observed in ceramics with CuO-MnO₂ addition. The parameter ε _r increases with increasing sintering temperature, and Q _f is effectively promoted by CuO-MnO₂ addition. Higher CuO-MnO₂ content would make τ_f value more positive. Meanwhile, ε _r value of 30.5, Q _f value of 63 200 GHz and τ _f value of 0.5 ppm/°C were obtained for 0.5Ba(Mg_1/3Nb_2/3)O₃-0.5Ba(Ni_1/3Nb_2/3)O₃ ceramics with 0.5 wt% CuO-0.5 wt% MnO₂ addition sintered at 1 330 °C for 4 h.
