Abstract
Structural ceramics based on silicon nitride, silicon carbide, and transformation-toughened zirconium oxide are potential candidates for advanced heat engines. Flaw populations, introduced during processing, currently limit their reliability. Processing steps responsible for common flaw populations will be discussed. It will be shown that new processing steps, based on colloidal powder treatments, combined with second phase engineering can increase fabrication reliability.
