Low-temperature sintered microwave dielectric ceramic material as well as preparation method and application thereof
The invention discloses a low-temperature sintering microwave dielectric ceramic material, a preparation method of the low-temperature sintering microwave dielectric ceramic material and application of the low-temperature sintering microwave dielectric ceramic material in preparation of low-temperature co-fired ceramic with metal Ag as an electrode. The chemical general formula of the low-temperature sintering microwave dielectric ceramic material is Zn < 1.92 > Cu < 0.08 > GeO < 4-y > wt.% B2O3, and y is 0.25-1; the sintering temperature of the ceramic material is below 960 DEG C and meets the co-firing condition with a metal electrode Ag (the melting point is 961 DEG C), and the Zn < 1.92 > Cu < 0.08 > GeO4 + 0.5 wt.% B2O3 ceramic material shows good dielectric properties when co-fired with the silver electrode at 940 DEG C: epsilon r = 7.38, Q * f = 108500 GHz and tauf =-25.3 ppm/DEG C; after being overlapped with a conductive electrode, the material can be subjected to multi-layer co-firing to prepare a miniaturized, integrated, multi-adaptive, low-cost and large-scale electronic component; the chemical composition and the preparation process are simple, and can be used for industrial production.
