US Patent 7556703 Method of bonding ceramics structures

A method of bonding at least a first ceramics structure (101) to a second ceramics structure (102), which includes the steps of applying a pressure to the first ceramics structure (101) and the second ceramics structure (102) in such a direction that these structures move close to each other with a bonding material layer (110) interposed between the first ceramics structure (101) and the second ceramics structure (102) (FIG. A), removing a bonding material (111a) extruded from the bonding material layer (110) to an end face of a stacked body including the first ceramics structure (101) and the second ceramics structure (102) by the application of the pressure thereto (FIG. B), drying a bonding material (111b) near the end face of the stacked body (120) after the extruded bonding material (111a) is removed (FIG. C), and drying the entire part of the stacked body (120).
