Low softening point metallic oxide glasses suitable for use in electronic applications

摘要

This invention presents a series of glasses which possess low softening points, high resistance to recrystallization and good durability in the presence of moisture. The glasses are contained within oxides of silver, vanadium, tellurium, and lead and have glass transition temperatures below 260 DEG C, and are useful in electronic applications such as die attach adhesives and sealing glasses.
