Abstract:
1. A method of making a vacuum insulated glass (VIG) unit, the method comprising: providing a first substrate; applying a frit slurry paste around edges of the first substrate; providing a second substrate such that the first and second substrates are substantially parallel and spaced apart from one another and such that the frit slurry paste is provided around edges of the second substrate; firing the frit slurry paste to create an edge seal; and at least partially evacuating a cavity formed between the first and second substrates, wherein the frit slurry paste has a bulk viscosity of 20,000-100,000 cps and comprises: wherein the frit slurry paste has annealing, softening, and working temperatures less than about 470 degrees C. and that all lie within a range of about 120 degrees C. of one another.
