ABSTRACT:
A barium-lithium-alumina-borate glass frit includes the following by weight on an oxide basis: 10.5-16.7% BaO; 10-11% Li.sub.2 O; 2-3% Al.sub.2 O.sub.3 ; and 70-77% B.sub.2 O.sub.3. The frit can be fired, i.e., fused from powdered form to solid sealing glass, at low temperatures, e.g., about 530.degree. C. Firing can take place in an atmosphere which is inert, oxidizing, or reducing. After firing for a sufficient time, e.g., 3 hours, the sealing glass becomes fully devitrified. The devitrified sealing glass has an expansion coefficient substantially the same as that of window glass, i.e., about 90 .times. 10.sup.-7 /.degree. C. The devitrified sealing glass can be reheated to temperatures in excess of 530.degree. C without deterioration or strains developing in a sealed joint.
