This paper describes the preparation, application, maturing, and fired properties of ceramic adhesives. The great majority of ceramic adhesives are based on a glass-type bond similar to that found in porcelain enamels and ceramic coatings. Using a frit as the basic constituent, the adhesives are applied to clean metal surfaces and fired to produce the bond. The adhesives resulting from this process retain a useful strength at temperatures of 1000°F. or higher. A process for combining ceramic adhesives and brazing alloys is also described. This combination has produced joints superior in strength to straight ceramic adhesives and comparable in strength to standard brazed specimens.
