The Ca3WO6 ceramic was prepared by solid state reaction method and can be well densified at above 1,260°C for 2h in air. All the XRD patterns can be fully indexed as a single-phase monoclinic structure (space group P21/n). The sharp Raman vibration mode at 810cm−1 suggests the long range order in the Ca3WO6 structure. The best microwave dielectric properties can be obtained in ceramic sample sintered at 1,275°C for 2h with a permittivity ~15.3, a Qf value ~29,200GHz and a TCF value about −30ppm/°C. Applying the oxide additivity rule, the calculated permittivity agrees well with the measured value. This kind of ceramic might have some potential value for microwave application for its good microwave dielectric behavior. The (Ca1/2W1/2) complex cations holding the site of Ti4+ in perovskite structure would introduce many new systems in complex perovskite compounds in the future.
