Oxide - glasses having low glass transition temperatures -.

摘要

PbO-B2O3-Ag2O glasses having a preferred weight ratio range of 76-88:10-15:2-10 have glass transition temperatures of less than 300 DEG C and are especially useful for adhering together ceramic substrates such as for attaching integrated circuits to ceramic substrates. The glasses can be formulated with Ag particulates and organics and applied as pastes to provide conductive adhesives.
