Abstract
The present disclosure relates to a low temperature-calcined lead-free glass frit and paste, and a vacuum glass assembly using the same. The glass frit according to the present disclosure has a novel component system comprising V2O5, TeO2, CuO, BaO, one or more of Ag2O and Bi2O3, ZnO, and one or more of SnO and MoO3 at a characteristic composition ratio according to the disclosure, whereby the glass frit can replace a lead-based glass composition of the related art, can be calcined at a low temperature of 350° C. or lower and can ensure excellent chemical durability.
