N2 - A new low-temperature fired dense (1 – x)BaMoO 4 –xBa 3 (VO 4 ) 2 (BM–BV) composite ceramics were prepared by a standard solid-state reaction process. The microstructure and phase composition were characterized by scanning electron microscopy and X-ray diffraction analysis. In this system, the consequences explained that BM and BV crystal phases are coexisted perfectly. With the BV addition increase, the ε r and the Q × f increase first and then decrease, and temperature coefficient of dielectric constant can be adjusted to nearly zero. In particular, the 0.48BM–0.52BV microwave dielectric ceramics sintered at 950 °C for 4 h possesses optimal dielectric performance: ε r = 11.9, Q × f = 43613 GHz and τ f = 0.38 ppm/°C.
