The Ba3(VO4)2-xZnMoO4 ceramics have been prepared by the conventional soli state reaction method and the effects of different contents of ZnMoO4 on the microwave dielectric properties and the microstructures of Ba3(VO4)2-xZnMoO4 compound ceramics have been investigated. The X ray diffraction (XRD) test results indicated that Ba3(VO4)2 and ZnMoO4 phase coexist in the composite, and no secondary phases can be detected, having a good compatibility. The near zero temperature coefficients of the resonant frequency (τf) could be achieved by adjusting the relative content of the two phases owing to their opposite τf values. When x=8%, the sintered temperature of prepared ceramics reduced to 850 ℃ and exhibited desirable microwave dielectric properties of the quality factor Q×f≈26 400 GHz, dielectric constant εr≈13, and resonant frequency temperature coefficient of τf≈+3 μ℃-1.
