In this study, the novel temperature-stable (1-x)Ag2MoO4-xAg(0.5)Bi(0.5)MoO(4) microwave dielectric ceramics were prepared by a modified solid-state reaction method. The phase composition, microstructures and microwave dielectric properties of the (1-x)Ag2MoO4-xAg(0.5)Bi(0.5)MoO(4) ceramics were investigated. All the compounds can be sintered well at ultra-low temperatures (< 540 degrees C). The XRD and SEM analysis indicate that the Ag2MoO4 and the Ag0.5Bi0.5MoO4 can coexist with each other. When x = 0.65, the ceramics exhibit the best microwave dielectric properties with a relative permittivity of 23.9, a Q x f value of 16,200 GHz (at 7.3 GHz) and a near-zero TCF value of -2.4 ppm/degrees C at 520 degrees C. The results indicate that temperature-stable (1-x)Ag2MoO4-xAg(0.5)Bi(0.5)MoO(4) ceramics are promising candidates for low temperature co-fired ceramics (LTCC) applications.
