Abstract

A method for manufacturing a connection between two ceramic parts comprises: providing a first ceramic part and a second ceramic part; providing an active hard solder, or active braze, on at least one surface section of at least one of the ceramic parts; and heating the active hard solder, or active braze, in a vacuum soldering, brazing process. The entire active hard solder, or active braze, for connecting the first and second ceramic parts is provided in such a manner that at least one surface section of at least one of the ceramic parts, preferably both ceramic parts, is coated by means of gas phase deposition of the alloy of the active hard solder, or active braze.
