Metal Oxide Nanopowders for the Production of Transparent Windows
Agency / Branch:
DOD / USAF
This STTR Phase I program is focused on evaluating both fine-grained alpha-alumina and polycrystalline YAG materials for utilization as visible and UV-transparent windows in advanced propulsion systems. These applications require improved window materials that provide for higher temperatures and pressures, along with low energy losses and lower weight; both fine grained alumina and ceramic YAG have the potential to meet these demands. High purity nanosized alpha-alumina and YAG powders will be produced and consolidated into transparent samples using proven techniques. These materials will be characterized and evaluated in terms of their applicability in advanced propulsion systems. In the Phase II program, the work will be directed at further refinement and improvement of the material properties, scaling up of the powder production processes and continued evaluation of the material properties, including the high temperature stability, corrosion resistance and irradiation response.
