Provided with a glass composition including a network-former oxide composed of any one of or both of B2O3 and V2O5 of 20-80% by weight, ZnO of 0-60% by weight and BaO of 0-80% by weight, wherein at least one of ZnO and BaO is included as an essential ingredient. The present invention is a glass material for use in sealing, which is of lead-free series, can be used for sealing at a low processing temperature and within a wide temperature range, has a low thermal expansion coefficient, superior adhesion, superior sealing processability, superior adherence, superior chemical stability, superior strength and the like and comprises sufficient practical performance to substitute for lead glass.
The lead-free glass material for use in sealing which has a glass composition composed of V2O5 of 25-75% by weight, ZnO of 0-45% by weight and BaO of 15-55% by weight.
A lead-free glass material for use in sealing, which has a glass composition consisting essentially of (A) 1-60 parts by weight of one or both of TeO2 and Bi2O3 and (B) 100 parts by weight of said composition being an oxide consisting essentially of 25-75% by weight V2O5, 0-45% by weight ZnO and 15-55% by weight BaO.
A lead-free glass material for use in sealing consisting essentially of a refractory filler mixed with glass powder, said glass powder consisting essentially of V2O5 of 25-75% by weight, ZnO of 0-45% by weight and BaO of 15-55% by weight.
A lead-free glass powder paste for use in sealing consisting essentially of V2O5 of 25-75% by weight, ZnO of 0-45% by weight and BaO of 15-55% by weight.
A lead-free glass mixed powder paste for use in sealing including a refractory filler added to a glass powder paste, said glass powder paste consisting essentially of V2O5 of 25-75% by weight, ZnO of 0-45% by weight and BaO of 15-55% by weight.
A lead-free glass powder paste for use in sealing consisting essentially of (A) 1-60 parts by weight of one or both of TeO2 and Bi2O3 and (B) 100 parts by weight of said paste being an oxide consisting essentially of 25-75% by weight V2O5, 0-45% by weight ZnO and 15-55% by weight BaO.
A lead-free glass mixed powder paste for use in sealing including a refractory filler added to a glass powder paste, said glass powder paste consisting essentially of (A) 1-60 parts by weight of one or both of TeO2 and Bi2O3 and (B) 100 parts by weight of said paste being an oxide consisting essentially of 25-75% by weight V2O5, 0-45% by weight ZnO and 15-55% by weight BaO.
