Ultra High Temperature Ceramics For Aerospace Applications

Ultra high temperature ceramics are a class of refractory ceramics that offer excellent stability at temperatures exceeding 2000 c being investigated as possible thermal protection system materials coatings for materials subjected to high temperatures and bulk materials for heating elements.

Ultra high temperature ceramics for aerospace applications. Temperatures above 1600 c and possibly exceeding 2200 c will be described as an ultra high temperature region to differentiate unique thermo mechanical and thermo chemical demands of aerospace applications. Ultra high temperature ceramics for aerospace applications the open aerospace engineering journal 2010 3. Ultra high temperature ceramic uhtc materials are assuming an increasing importance in aerospace research because their high temperature capabilities make them interesting to develop components for extreme applications such as thermal protection systems of hypersonic or atmospheric reusable re entry vehicles specific components for propulsion combustion chambers engine intakes or rocket nozzles. The ultra high temperature ceramics uhtcs are of great interest for different engineering sectors and notably the aerospace industry.

In aerospace applications ceramics are primarily found in engine and exhaust systems thermal protection shields and structures for ultra high speed flying objects.
