ABSTRACT:
A connection between non-oxidic ceramic (ceranox) material and metallic material is formed by providing a recess in the metallic material having oppositely facing internal surfaces between which is positioned a portion of a ceramic component with intervening gaps. The gaps are filled with a high temperature solder. The solder is preferably melted into position between the metallic and ceramic components in an evacuated soldering oven according to a stepped temperature profile.
