Silicon Nitride Joining.

Abstract

The results obtained in the third year of a continuing investigation into a method of joining silicon nitride with an oxide glass are described. Mechanical behavior of joints at room temperature and the criteria for strong joints are detailed. Two approaches were taken to strengthen the joints: heat treatments to crystallize the glass in the joint and surface preparation. The high temperature behavior of various Si3N4/glass systems was investigated by means of high temperature mechanical tests, mass spectrometry, theoretical calculations, and mass transport studies.
