METHOD FOR ELECTRICALLY BONDING CERAMIC AND HEATING MEMBER FOR BONDING

PURPOSE:To electrically bonding ceramic without causing residual stress by bringing ceramics into press-contact with both surfaces of a conductive ceramic plate via the bonding agents respectively and electrifying the conductive ceramic plate to heat it. CONSTITUTION:Ceramics 1A, 1B are allowed to abut on both surfaces of a conductive ceramic plate 3 via the bonding agents 2A, 2B respectively and pressed with prescribed pressure P to allow them to adhere without a gap. The electrodes 4A, 4B are allowed to abut on the projected both end parts of the conductive ceramic plate 3 respectively and the lead wires 5A, 5B for electrification are connected therewith. In this case 1A and 1B may be the same or different kind of ceramics. When electrifying the conductive ceramic plate 3 in this constitution, Joule's heat is generated and the bonding parts are heated and the ceramics 1A, 1B are allowed to react with the conductive ceramic plate 3 and with the bonding agents 2A, 2B respectively. Thereby the ceramics 1A, 1B are firmly bonded in a short time via the conductive ceramic plate 3.
