PRODUCTION OF JOINED BODY COMPOSED OF CERAMICS AND METAL

摘要

PURPOSE:To remarkably enhance the productivity and produce a joined body of ceramics to a metal without impairing the surface conditions of the metal and joining strength of the metal to the ceramics. CONSTITUTION:This method for producing a joined body composed of ceramics and a metal is to superimpose 2 or 3 or more units comprising each laminate prepared by superimposing ceramics to a metallic circuit and/or a metallic plate for forming the metallic circuit with or without interposing a brazing filler material containing an active metal as one unit through spacers composed of ceramics having a nonoxide layer on the surface thereof and heat the resultant superposed units comprising the laminates in thermally joining the superimposed units comprising the laminates.
