Low-temperature sintering temperature stable stannate microwave dielectric ceramic material
The invention relates to a low-temperature sintering temperature stable stannate microwave dielectric ceramic material. A material phase of the ceramic material comprises the following raw materials: 35.1wt%-79.1wt% of Li2Mg3SnO6 and the balance of Li2SnO3, wherein the dielectric constant of the ceramic material is 14.2-14.7; the quality factor is 51300-78300GHz; and the temperature coefficient of the resonance frequency is -9.1ppm/DEG C to 4.6ppm/DEG C. The sintering temperature of the low-temperature sintering temperature stable stannate microwave dielectric ceramic material is 840-920 DEG C, so that the defects that the ceramic material is high in sintering temperature and slightly large in temperature coefficient of the resonance frequency are overcome; the temperature stability of the material is ensured; the raw materials used for preparing the ceramic material are abundant and low in cost; industrial production is facilitated; and the low-temperature sintering temperature stable stannate microwave dielectric ceramic material can be widely applied to preparation of microwave devices such as a low-temperature cofired ceramic system, a GPS antenna, a filter for a wireless local area network and a multi-layer dielectric resonator.
