Abstract

Modified processing methods and additives allow for the development of SiC with reduced grain size microstructures and improved mechanical properties. A surfactant based additive system for carbon and boron was coupled with particulate aluminum nitride additions to modify grain boundary behavior and grain growth. Near theoretical densities were attained at lower hot pressing temperatures ranging between 2000°C and 2200°C. Microscopic evaluation indicates a decrease in grain size from 5-6 μm at 2200°C to 2-3 μm at 2000°C with an increase in hardness.
