Abstract
The present invention provides a method for brazing a metal object to a ceramic surface defining a recess for receiving the metal object where the space between the metal object and the ceramic surface defining the recess inhibits the establishment of the oxygen depleted environment necessary to establish a reliable braze joint. The present invention includes the use of a material having a high affinity for oxygen that is positioned adjacent to the space between the metal object and the ceramic surface defining the recess and serves to pull or draw oxygen from the space to establish the oxygen depleted environment required to produce a reliable braze joint.
