摘要：

Ultra-low firing microwave dielectric ceramic Pb2MoO5 with monoclinic structure was prepared via a conventional solid state reaction method. The sintering temperature ranged from 530℃ to 650℃. The relative densities of the ceramic samples were about 97% when the sintering temperature was greater than 570℃. The best microwave dielectric properties were obtained in the ceramic sintered at 610℃ for 2 h with a permittivity ~ 19.1, a Q×f value about 21,960 GHz (at 7.461 GHz) and a temperature coefficient value of -60 ppm/℃. From the X-ray diffraction, backscattered electron image results of the co-fired samples with 30 wt% silver and aluminum additive, the Pb2MoO5 ceramics were found not to react with Ag and Al at 610℃ for 4 h. The microwave dielectric properties and ultra-low sintering temperature of Pb2MoO5 ceramic make it a promising candidate for low temperature co-fired ceramic applications.
