Abstract
A three-layer clad plate or a laminated sheet comprising a core piece made of aluminum or its alloy and surfaces made of an aluminum-silicon alloy is inserted between the bonding surfaces of ceramics or between the bonding surface of a ceramic and that of a metal. The resulting structure is maintained at a bonding temperature lower than the melting point of aluminum or its alloy and higher than the solidus of the aluminum-silicon alloy while pressurizing the inserting material, thus bonding the ceramics to each other or the ceramic to the metal.
