Abstract
A vacuum insulating glass (IG) unit is provided with an indium inclusive peripheral/edge seal, preferably deposited originally in the form of a viscous slurry. The use of such material for the edge seal permits lower processing temperatures to be used. This in turn may in some embodiments allow thermally tempered glass to be used in IG units without losing substantial temper during the fabrication process, permit certain low-E coatings to be used, and/or allow a lesser number of supporting pillars to be used.
Claims12
A thermally insulating glass panel comprising:
- first and second spaced apart thermally tempered glass substrates defining a low pressure space therebetween;
- an indium inclusive peripheral seal interconnecting said first and second spaced apart glass substrates so as to hermetically seal said low pressure space between said substrates;
- and
- wherein said first and second glass substrates retain at least about 70% of their original tempering strength at a point in time after said peripheral seal is formed between said substrates.
