  • Sealing glass compositions using ceramic composite filler
    Patent number: 5510300
    Abstract: The present invention relates to low temperature sealing glass compositions using ceramic composite filler useful for sealing alumina ceramic package, in particular, to compositions for hermetic-sealing cap and base of alumina package which consists of a solid PbO-B.sub.2 O.sub.3 glass powder and a filler selected from zinc zirconium silicate composite or magnesium aluminum zirconium silicate composite as a low thermal expansion ceramic composite. The used composite filler composes of zircon and willemite crystal phase or zircon and cordierite crystal phase uniformly mixed on the filler and has the low thermal expansion coefficient of 20.degree..about.40.degree..times.10.sup.-7 /.degree.C.
