Abstract
The forming of hermetic seals suitable for sealing materials having dissimilar thermal expansions which are formed by reacting an effective amount of a metal powder, selected from the group consisting of aluminum, antimony and zirconium, with glass frit having a softening point of <750.degree. C. and a coefficient of thermal expansion sufficiently compatible with the materials being sealed to yield seals characterized by a coefficient of thermal expansion closely matching or similar to those of the materials being sealed and a use temperature equal to or greater than 1000.degree. C. The seals of this invention are particularly suitable for bonding ceramic to ceramic.
