Summary

Non-oxide ceramics, such as silicon carbide, offer attractive properties for many uses at elevated temperatures where brazed joints become brittle and unreliable. One alternative joining method is the pyrolysis of preceramic polymers to amorphous, non-oxide materials that bond readily to ceramics and metals. These materials have the further advantage that they can be processed at lower temperatures than brazes or reaction-based methods. Shrinkage and evolution of gaseous species during pyrolysis of preceramic polymer-based joints, however, can give rise to strength limiting defects. This talk will describe approaches to controlling stresses that arise during joining with a typical preceramic polymer, allyl-hydridopolycarbosilane.
