GLASS PACKAGE THAT IS HERMETICALLY SEALED WITH A FRIT AND METHOD OF FABRICATION

摘要

A hermetically sealed glass package preform is provided comprising a glass substrate; a frit comprising 65 - 100 wt.% of a base glass and about 0 - 35 wt.% of a filler; wherein the base glass comprises: about 0 - 5 mole % K₂O; about 0 - 35 mole % Sb₂O₃; about 0 - 20 mole % ZnO; about 10 - 40 mole % P₂O₅; about 10 - 60 mole % V₂O₅; about 0 - 5 mole % TiO₂; about 0 - 5 mole % B₂O₃; about 0 - 5 mole % SiO₂; about 0 - 5 mole% WO₃; and about 1- 10 mole % of a metal oxide selected from the group consisting of Fe₂O₃, Nd₂O₃, La₂O₃, Ce₂O₄, Pr₆O₁₁, Er₂O₃, and CeO₂; wherein the base glass has a mean particle size distribution of less than about 3 µm; and wherein the filler has a mean particle size distribution of between about 3 and 7 µm. The frit is sintered in an atmosphere less oxidizing than air at a temperature of between about 39O °C to 415 °C.
