Abstract

Not Available In Phase I of the program, we will demonstrate fabrication of IR-transparent, dense, nanocrystalline (< 100 nm) aluminum oxide (Al2O3) discs by microwave sintering of nanopowder compacts. Such a material is a potential replacement for the more expensive sapphire (single crystal Al2O3) that is used in high speed heat seeking missiles. NEI is a manufacturer of nanopowders, and our collaborators at PennState University have developed a unique microwave sintering technology, especially suited for processing large and complex shaped transparent components. Starting from coarse grained powders, fully dense, transparent ceramic pellets that are 10 mm in diameter and 1 mm thick, have been formed by microwave sintering. In Phase I of the program, Al2O3 nanopowders will be produced by our patented Combustion Flame - Chemical Vapor Condensation process, compacts that are 10 mm in diameter and 1.5 mm thick will be formed, and microwave sintered to theoretical density. The optical properties and structure will be characterized in Phase I. The sample size will be scaled and properties will be optimized in Phase II. In addition, mechanical, thermal and optical properties will be evaluated and a property database for these materials will be created. IR-transparent nanocrystalline ceramics will be produced on a commercial basis and marketed in Phase III of the program.
