Abstract
An article of manufacture that has a component capable of being sealed with a copper aluminosilicate glass. The sealing glass has a coefficient of thermal expansion (CTEs) of in the range between 20-82×10-7/° C., over a range of 25-500° C.) and a softening points in the range of 660-1000° C. The glass has a composition consisting essentially, in terms of weight percent on an oxide basis, of 35-68 SiO , 3-25 Al O , 2-26 B O , 0-20 R O, 0-30 RO, 2-33 CuO, 0-4 F, 0-10 M O , where R O is an alkali oxide selected from the group consisting of Li O, Na O, and K O, and RO is an alkaline earth oxide selected from the group consisting of CaO, MgO, ZnO, SrO, and BaO, and M O is a transition metal oxide selected from the group consisting of Co O , TiO , NiO, MnO , and Fe O . The present invention also pertains to a method of sealing the article.
