Improving the thermal shock resistance of zirconium diboride ceramics

Keywords and Phrases

Reactive hot pressing


"This research has focused on improving the thermal shock resistance of zirconium diboride (ZrB₂) based ceramics. Despite the development of ZrB₂-based materials for their use in high temperature applications, the thermal shock properties have not been investigated extensively. Materials expected to be used in ultra-high temperature environments (i.e. rocket propulsion and hypersonic flight) will be required to maintain structural integrity despite the extreme temperatures and heating rates associated with these applications. The fundamental hypothesis of this Ph.D. study is to determine if the introduction of a ZrB₂-based ceramic into a functionally engineered fibrous monolith composite improves thermal shock resistance"--Abstract, page 1.
