Patent ID: 7883599

Claim:
A method for bonding ceramic structural bodies, the method comprising: forming a set of ceramic structural bodies by applying a ceramic bonding agent between bonding surfaces of the structural bodies; disposing elastic sleeves on a peripheral surface of the set of ceramic structural bodies; placing the ceramic structural bodies with the elastic sleeves in a tubular container and disposing an elastic sheet between the elastic sleeves and the tubular container; and charging a hydrostatic pressure medium between the tubular container and the elastic sheet to apply pressure to the set of ceramic structural bodies, wherein charging the hydrostatic pressure medium includes: pressing the elastic sleeves into contact with the ceramic structural bodies by compressing the elastic sleeves at a pressing speed of about 50-100 kPa/sec, and applying pressure to the ceramic structural bodies in contact with the elastic sleeves at a pressing speed of about 10-50 kPa/sec, wherein the ceramic structural bodies have a honeycomb structure.
