  • Patent number: 8075961
    Abstract: A glass bonding material contains vanadium and phosphor as main glass components, and comprises in amounts converted as oxides of the elements in the components, 45 to 60% by weight of V2O5, 15 to 30% by weight of P2O5, 5 to 25% by weight of BaO, or contains a glass comprising at least vanadium, phosphor, barium and antimony, wherein the glass comprises in amounts converted as oxides, 15 to 35% by weight of BaO and Sb2O3 in total, and a weight ratio of BaO/Sb2O3 or Sb2O3/BaO is 0.3 or less.

  • Patent number: 8071183
    Abstract: A sealing glass of a low melting point phosphate glass composition contains 15 to 35% of BaO and Sb2O3 (in total) and the ratio by weight of BaO to Sb2O3 or Sb2O3 to BaO is 0.3 or less. Particularly the transition metal is vanadium and the glass contains V2O5 of 45 to 60 wt % as vanadium oxide and P2O5 of 15 to 30 wt % as phosphorus oxide. The bonding material is a mixture of a filler and a vanadate-phosphate glass that contains V2O5 of 45 to 60%, P2O5 of 20 to 30%, BaO of 5 to 15%, TeO2 of 0 to 10%, Sb2O3 of 5 to 10%, and WO3 of 0 to 5%. The particle size of the filler is in the range of 1 to 150 ?m and the ratio of filler is 80% by volume or less of the adhesive glass.
