Title: GLASS-CERAMIC SEALS FOR CERAMIC MEMBRANE CHEMICAL REACTOR APPLICATION
Abstract:
Glass-ceramic sealants (1) for ceramic membrane reactors (2), ceramic membrane sealed to holders or substrates (3) and methods of making seals between two ceramic materials or between a ceramic and a metal or a metal alloy are provided. These sealants (1) combine silicate glass-ceramic materials with selected metal oxides and, optionally, materials similar or identical to the materials being sealed, and employ thermal processing so that the resultant materials will have a thermal expansion coefficient that substantially matches the thermal expansion coefficients of the two materials. Surfaces of the ceramic sealant that are exposed to reactive atmospheres can be protected by providing a metal or metallic alloy layer (20) over the ceramic seal (1).
