Vanadium-based temperature-stable ultralow-temperature sintered microwave dielectric ceramic material and preparation method thereof
The invention discloses a vanadium-based temperature-stable ultralow-temperature sintered microwave dielectric ceramic material and a preparation method thereof. The ceramic material consists of a material shown by a general formula (Ba1-xSrx)V2O6, wherein x is 0.35-0.55; and the ceramic material has good microwave dielectric properties (the dielectric constant is 9.3-11.1, the quality factor is 10000-14900GHz, and the temperature coefficient of resonance frequency is -10.2 to +9.1ppm/DEG C), is low in sintering temperature (575-650 DEG C), and can be matched and co-fired with an Al electrode. The vanadium-based temperature-stable ultralow-temperature sintered microwave dielectric ceramic material disclosed by the invention is prepared by virtue of traditional solid phase reaction, is rich in used raw materials, low in cost and beneficial for industrial production, and can be widely applied to the manufacturing of microwave devices including a low-temperature co-fired ceramic system, a multilayer dielectric resonator, a wave filter, a microwave substrate and the like.
