Abstract:
A fusion seal between two surfaces, and a material to produce the seal, consist essentially of 60-90 percent by weight of a SnO-ZnO-P2O5 glass frit and 10-40 percent by weight of a mill addition including 0-30% alumina, 0-40% zircon, the total ofalumina and zircon being 10-40% and 0-15% of a further additive that reduces theeffective CTE of the seal, the mill addition being present in a sufficient amount to provide a sealing material having a set point of at least 300.degree.C. The effect of the mill addition in a fusion seal finds particular application in uniting the faceplate and funnel members to form a cathode ray tube envelope.
Abstract:
The present invention is directed to a method for synthesizing highly crystalline pollucite articles at temperatures not exceeding 1650.degree.C. The method comprises two general steps: (a) a glass frit is prepared having a composition varying from approximately the stoichiometry of Cs2O-2SiO2 to approximately the stoichiometry of Cs2O.4SiO2 with, optionally, up to 5% A12O3; and (b) that glass frit is reacted at a temperature between about 1000.degree.-1650.degree.C with an A12O3-containing material in sufficient amounts to yield a final product having a stoichiometry approximating that of pollucite.

Abstract:
A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package particularly using an OLED is described herein. In one embodiment, the hermetically sealed glass package is manufactured by providing a first substrate plate and a second substrate plate. The second substrate contains at least one transition or rare earth metal. A sensitive thin-film device that needs protection is deposited onto the first substrate plate. A laser is then used to heat the doped second substrate plate such that a portion of it swells and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the thin film device. The second substrate plate is doped with at least one transition metal such that when the laser interacts with it there is an absorption of light from the laser in the second substrate plate.
