Recent Developments in High Performance Ceramics
Abstract
Newly developed ceramic materials, fabrication processes, and advances in brittle materials design capability are having a significant impact on our ability to utilize ceramics as substitute materials. This paper will briefly review ceramic materials and their methods of fabrication. We will then consider the use of silicon nitride and silicon carbide ceramics in hot flow path components of gas turbines. Emphasis will be on the advantages of ceramics of this application, materials, and progress to date. Application of single and polycrystalline ceramics to optical systems such as high energy lasers will be reviewed. The detailed characterization and manipulation of grain boundaries in ceramics will be seen to be of great importance in both the high temperature structural and advanced optical areas of application.
