Techniques were developed to produce reliable ceramic-ceramic joins and analytical models were developed to predict the mechanical performance of the joins at room and elevated temperatures. Si{sub 3}N{sub 4}-4% Y{sub 2}O{sub 3} (Norton NCX-5100) and {beta}-Sic (Norton NCX-4500) were joined to themselves in the green state prior to final densification. The joins and controls were chemically and mechanically characterized at room and elevated temperatures to prepare the data banks for analytical modeling. Analytical models combining finite element and probabilistic software were developed that are capable of predicting the reliability of the joined components under fast fracture and creep.
