摘要	Low-temperature-fired microwave ceramics are key to realizing the integration and miniaturization of microwave devices. In this study, a facile wet chemical method was applied to synthesize homogenous nano-sized CaF powders for simultaneously achieving low-temperature sintering and superior microwave dielectric properties. Pure CaF ceramics sintered at 950 °C for 6 h with good microwave dielectric properties (ε = 6.22, Q×f = 36,655 GHz, and τ = −102 ppm/°C) was achieved. The microwave dielectric properties of the CaF ceramics were further improved by introducing LiF as a sintering aid. The sintering temperature of CaF-based ceramics was effectively lowered from 950 °C to 750 °C with 10 wt% LiF doping, and excellent microwave dielectric properties (ε = 6.37, Q×f = 65,455 GHz, and τ = −71 ppm/°C) were obtained.
