ABSTRACT:
A bonded ceramic structure is fabricated by inserting a plurality of ceramic tubular members respectively in holes formed in a perforated ceramic plate member and bonding the same to the perforated ceramic plate. A clearance is formed between the outer circumference of the tubular member or that of a ceramic sleeve fitted on the tubular member, and the surface of the hole, and the clearance is filled up with a bonding material forming a bonding layer to join the tubular members to the plate by a high strength at a high positional accuracy. A method of fabricating such a bonded ceramic structure spreads a fusible bonding material on at least one major surface of the plate member, inserts the tubular members in the holes of the plate member, and fuses the bonding material so that the fused bonding material flows into the clearance between the surface of each hole and the tubular member to form a bonding layer continuously extending over the surface of the plate and in the clearances.
