Abstract
A glass frit according to this application may include a composition of PO, VO, TeO, CuO, ZnO, and BaO configured to replace a conventional lead glass composition and enable a low temperature calcination. A coefficient of thermal expansion (CTE) of the glass frit may be matched with that of a glass substrate. The composition may not include an inorganic filler or at least reduce a content of an inorganic filler to reduce or prevent separation and breakage and to improve durability. The glass frit may be used as a paste for a vacuum glass assembly.
