Summary

The degradation of strength of clay-bonded SiC-based filter materials in water vapor environment was investigated. Two types of filters were exposed to thermal cycling and/or high-temperature water vapor in controlled laboratory environment. The decrease in strength as well in Young's modulus and fracture toughness was observed for the material with better initial strength. There were no significant changes in strength or fracture toughness of the originally less strong material but decrease in Young's modulus was found.
