A microwave dielectric BaCu2V2O8 ceramic with a low intrinsic sintering temperature was synthesized by a solid-state sintering process. The influences of sintering process on the crystal phase composition, microstructure, relative density, and microwave dielectric properties of BaCu2V2O8 ceramic were studied utilizing scanning electron microscopy and an x-ray diffractometer. The crystalline phase of BaCu2V2O8 was the only one phase found in ceramic. The sample fired at 740°C for 6 h had the optimal microwave dielectric properties (εr= 13.5, Q × f = 46,300 GHz and τf = − 41.5 ppm/°C). The results mean that electronic devices fabricated by low temperature co-fired ceramic technology based on BaCu2V2O8 ceramic have potential applications in the high-frequency field.
