Abstract:

This Phase II SBIR ARMY project proposes the development/optimization and preliminary scale up of 7 in diameter hemispherical spinel domes (3.5 radius, 0.18 wall thickness, 160 degree aperture) through the combination of freeze casting (FC) technology with unique nanopowder coating technology commercialized by MER (NC-Spinel) for magnesium aluminate spinel (MgAl2O4) ceramics. These technologies allow for the production of spinel domes with high green density, green near net shape, no residual stress, that result in 99.99% Th.D. for the sintered domes minimizing the distortion and residual stresses on the sintered dome. The novel process requires less secondary machining after sintering to produce high quality transparent domes at a lower cost when compared to cold isostatic pressing (CIP) technology. MER successfully demonstrated this technology during Phase I.
