1. A method for producing a metal-brazing alloy-ceramic connection that is repeatedly subjected to changes in temperature in excess of 600° C. during use, in which the metal and ceramic are brazed to one another two-dimensionally using an active ductile brazing alloy by heating the metal, the ceramic and the active ductile brazing alloy,
characterized in that the metal and ceramic are arranged against one another in a displacement controlled manner in a non-vacuum atmosphere; and wherein the metal and alloy are selected from the group consisting of aluminum, nickel, zinc, silver, copper, gold and mixtures thereof and brass, and wherein the ceramic is selected from oxide ceramic and a carbide ceramic materials; and wherein the metal and ceramic are pressed against one another in a displacement controlled manner at a predetermined distance from one another during that phase in which the active ductile brazing alloy becomes soft, is soft or molten and/or hardened, while preventing active ductile brazing alloy from being pressed out of the region between the metal part and the ceramic part, to thereby provide a layer of active ductile brazing alloy with a minimum thickness of 0.2 mm and maximum thickness of 1.0 mm; and wherein the metal-brazing alloy-ceramic connection is fixed after heating until cooling down has progressed to the extent that any movement of the metal and the ceramic in relation to one another is prevented. |
