Abstract

Low-temperature-sintered Ba3(VO4)2–CaWO4 composite ceramics were prepared by cofiring mixtures of pure-phase Ba3(VO4)2 and CaWO4. The thermo-mechanical analysis revealed that the CaWO4 in the composite ceramic can significantly promote the densification process and lower the sintering temperature to ~900 °C. The X-ray diffraction results indicated that Ba3(VO4)2 and CaWO4 phases coexist in the sintered ceramics, and no secondary phases can be detected in the composite, implying the good chemical compatibility between the two phases. 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. The composite ceramics with 60 wt% CaWO4 sintered at 900 °C exhibited desirable microwave dielectric properties of the quality factor Q × f ~ 37,000 GHz, dielectric constant εr ~ 12, and τf ~ −1.4 ppm/°C.
