ABSTRACT:
A material for joining ceramics and metal plate comprises a titanium-copper type braze disposed adjacent to the ceramics, and a stress cushioning and brazing material. The material includes first and second nickel plates, and a tungsten plate between the first and second nickel plates. The first and second nickel plates and the tungsten plate operate as a stress cushioning material, while a titanium film, copper foil and the first nickel plate form the titanium-copper type braze. In the method, the ceramics, metal plate, stress cushioning and brazing material and braze are heated above a predetermined period of time under vacuum condition. In the present invention, the ceramics and the metal plate are joined with improved thermal resistance at a joint portion.
