Fluorophosphate glass - tungsten-doped tin with durability

摘要

As used herein, the tin is a tungsten-doped - fluorophosphate glasses have been described and shows moisture resistance, good heat resistance, the glass is suitable for low temperature sealing applications such as encapsulation of electronic components I have a low glass transition temperature. In one embodiment, a weight percent elemental basis, these glasses, Sn of 55-75%, P of 4-14, O 6-24%, 0.15-15% F and 4-22% I include the W of.
