The present invention is directed at a copper aluminosilicate glass, having coefficients of thermal expansion (CTEs) of between 20-82.times.10-7/.degree. C. (over a range of 25-500.degree. C.) and a softening points in the range of 660-1000.degree. C., being suitable for use as a sealing glass, especially for borosilicate glass, and having a composition consisting essentially, in terms of weight percent on an oxide basis, of 35-68 SiO2, 3-25 Al2O3, 2-26 B2O3, 0-20 R2O, 1-30 RO, 2-33 CuO, 0-4 F, 0-10 MxOy, where R2O is an alkali oxide selected from the gr...
1. A copper aluminosilicate glass having a composition, as expressed in weight percent on an oxide basis, that consists essentially of: about 48% to about 68% SiO2; about 3% to about 6% Al2O3; about 20% to about 26% B2O3; about 2% to about 10% CuO; 0% to about 30% RO; 0.05% to about 4% F; 0% to about 20% R2O; and 0% to about 10% MxOy; where RO is an alkaline earth oxide selected from the group consisting of CaO, MgO, ZnO, SrO, BaO; R2O is an alkali oxide selected from the group consisting of Li2O, Na2O, K2O; and MxOy is a transition metal oxide selected ...
